Re: Wireless Pre-N Router F5D8230-4..Beware

Customers have a rights to know everything about Belkin and its pre-standard products before wasting your time. These are comments from respected industry leaders and medias.

Pre-N Standard still needs to resolve from both business and technical's perspective.

Eric Demming and Belkin did not tell customers about its status and problems. They only trying to sell you cheap products.

Read these latest articles and decide who trying to sell you junks.

Bizmo -

This is really getting tiresome. You've been posting doom and gloom notes, as well as links to either the same articles, or to others that quote the first articles, over and over again.

You keep posting these in response to my posts about my personal experiences with other products, and the rationale for my decision to try Belkin's Pre-N products. Unfortunately, it appears that you have NOT read, or have not understood, the contents of my posts. You seem to be intent on discrediting Belkin and especially in attacking their Pre-N line of products.

Just to clarify the issue:

Belkin's Pre-N products have been certified as being compliant with 802.11b and 802.11g. THAT'S ALL. That's also the ONLY certification they claim. They explicitly state that these products are NOT intended to be compatible with whatever shape the eventual standard for 802.11n takes.

My interpretion of the name "Pre-N" is that this new technology that Belkin is offering ON TOP of their certified implementations of 11b and 11g is, perhaps, somewhere between the current standards (11g) and what we may expect to see in 11n sometime in the next 18 to 24 months. In case you haven't read up on this, there has been a lot of discussion about the idea of using "MIMO" (multiple in, multiple out) technology as part of the upcoming 802.11n standard. This is a way of using multipath signal reflections to actually extract MORE information from a signal than is currently done -- a novel approach, considering that multi-path has traditionally been a cause for distortion and interference in radio. However, if you do your homework, you'll find out the Belkin doesn't claim that even this part of "Pre-N" is going to be part of the 11n standard. They simply mention that they are taking advantage of a similar technique with their use of Airgo's chipset and core software.

That's it. No pretense that "Pre-N" is based on any upcoming 11n standard -- as even Belkin acknowledges that the 11n standard simply isn't a known quantity yet. NOBODY can claim compatibility with this future, yet-to-be-announced, standard -- and NOBODY DOES. It's that simple.

I'm starting to feel mighty silly responding to your repeated "warning" posts about Pre-N, but it seems that you have a strong desire to discredit Belkin and Pre-N. Many people come here to learn about various products and technologies -- and I feel something of a need to temper your dire warnings that seem to be based more on a personal bias against Belkin than anything else.

For the record:

Precisely as Belkin states, their "Pre-N" equipment is certified by the WiFi alliance as being compliant with 802.11b and 802.11g - period. On top of this, Belkin offers a proprietary MIMO mode (based on Airgo's technology), that allows Pre-N equipment to communicate farther and faster than standard 802.11g, when the devices on both ends of a connection are Pre-N. This is precisely analogous to what Broadcom has done with "Afterburner", and Atheros has done with "Super G". All three of these technologies are "non-standard", all three offer better-than-11g performance, and all three will only offer this benefit when equipment on both ends of the connection use the same proprietary technology.

Belkin's Pre-N is simply another alternative in the "better-than-11g-but-not-standards-based" market. Based on my experience to date, Pre-N works better, has better range, and is far more stable than Super G. I have no personal experience with Afterburner. However from what I have read (I believe it was a PC Mag lab test), Pre-N clocks the best range and throughput to date with a stock product packaged for the SOHO market.

Bizmo:

- If you can point us to an article or quote in which Belkin is saying something fraudulent -- please do so now.

- If you can point us to an article or quote in which Belkin claims that "Pre-N" will be compatible with the as-yet-undetermined 802.11n standard -- please do so now.

- Are you equally suspicious and angry that Atheros, DLink, Fujitsu, Aztech, Wistron, Airlink, OrangeWare, Senao, Netgear, Linksys, and MANY more companies world-wide are doing the exact same thing? Each sells devices that are 802.11b and 802.11g certified -- but also offer an enhanced proprietary mode that is FASTER than 11g. In case this wasn't apparent -- that's EXACTLY the same proposition that Belkin is offering with "Pre-N".

To everyone else:

I apologize if my reponses to Bizmo are prolonging this silliness -- that's not my intention.

However, I spent close to a year wrestling with my DLink di-624, a "super G" laptop card (dwl-g650) and a "super G" pc card (dwl-g520). I lost a couple of hundred hours to this, and found that although the Atheros technology is very promising, the implementation left a lot to be desired in terms of stability and customer support. I still own my DLink equipment, and would be thrilled if a new firmware release somehow made it all stable.

In the meantime, having given up a few weeks ago on my DLink setup, I opted to try Belkin's entry into the "more-than-11g" market. I've had it up and running for about 2 weeks now. In my experience, it has been everything that I had hoped the DLink equipment would be: faster than 11g, very solid and stable, and maintenance-free. That's only 2 weeks, so far -- and it took me a lot longer than that to become disenchanted with DLink, so who knows? Maybe the honeymoon won't last. But for the moment, I'm finding the Belkin F5D8230-4 "Pre-N" router and the corresponding notebook and pc cards to work very well indeed.

I don't expect these products to be 802.11n compatible when the standard is announced sometime in 2006. But I do expect them to offer me better-than-g performance for a long time to come -- especially since I have a lifetime warranty on the products and their performance, and I plan to exercise it if either should fail.

Since Bizmo likes to quote magazine articles, here are a few pretty good ones to look at:

»www.pcmag.com/article2/0 ··· 0,00.asp

»reviews.zdnet.co.uk/hard ··· 0,00.htm

»ecoustics-cnet.com.com/B ··· 672.html

In the end, I believe it comes down to a few key points:

1) the products are 802.11b and 802.11g certified, and are backward compatible with these product standards.

2) they cost a bit more than similar 802.11g and "enhanced G" products that compete in the same price range.

3) you should NOT purchase these with the expectation that they will somehow be compatible with an as-yet-unannounced standard for 802.11n, which will NOT be announced for another 12 to 18 months.

4) If you like being an "early adopter", you might find these devices appealing.

5) The lifetime product and performance warranty is an important plus in my mind.

That's it. As far as I can tell, there' no evil hidden agenda here. But if Bizmo can point us all to it, I'd be happy to learn about it. PLEASE BIZMO: if you have something new or constructive or fact-based to post about Belkin and Pre-N, especially if it's something that supports your notion that it's all a scam and should be avoided at all costs, THEN BY ALL MEANS POST THIS!

But please don't continue to bash Belkin and Pre-N here based on a personal agenda and bias.

i agree with you 100% jonazen, bizmo is obviously an inept idiot with regard to networking and i suspect any problems he has had in the past may have been solvable with the right knowledge and experience, i also suspect he would have had similar experiences with many of the products currently available. English is also obviously not his native language as his posts do not follow the thread he is responding too. he clearly has an axe to grind for belkin. i consider these forums to be SUPPORT! forums and his posts do nothing to help the people struggling with new hardware. Bizmo hasn't made a single constructive comment so as jonazen said .....

Bizmo put up or shut up! please keep your comments constructive and helpful

peoples demands of these complicated devices are different and no two setups will be identical which is why people have different experiences with devices. i had a call from a Friend asking me about a netgear wireless router so i decided to check out their support forum on this site and was surprised to see similar problems being discussed there. seems like belkins track record is the same as all the other manufacturers in this market.

i had problems with my router when it was first installed but with a little tweaking my system is now stable and it has currently been running for 7 days solid and i can see no reason why it wouldn't run 365 days solid. my only complaint with belkin is there phone support people don't seem too knowledgeable but sadly that seems typical for telephone support these days and I'm certain the same could be said for any of the other manufacturers

One question - does the Belkin Pre-n router support WDS, wireless distribution, like their G routers do?

As far as I can tell, this version of the firmware does not support WDS. You may recall that the WDS was added in the 802.11g routers via a firmware update, so it's quite possible that we'll see this eventually with the F5D8230-4 as well, although that's completely a matter of speculation right now. But for the moment, it doesn't appear to be in there...

Thanks for the detailed useful information jonazen. I have had the displeasure of trying three different brands of wireless router over the last two months (couldn't settle on one I was happy with). First was Netgear WGT624. Greatest range of the three - actually GREAT range now that I've compared to the others - but CONSTANT drops in connection - tried it all - Netgear support, traded for another WGT624, online forums, hired a network person - nothing worked. Finally traded it for a Linksys 54GS. Nice stable router, no bells and whistles but nice reasonable feature set, disappointing range compared to the Netgear. Traded for a Belkin Pre-N hoping it would match/exceed the range of the Netgear. It didn't. Very fast wireless connection when close to the router, still range not as good as Netgear. But I'm keeping it; I might get a Belkin Pre-N card to take full advantage of the range. I realized it would be less without the companion card, but I thought I'd give it a shot. Even without it though, the connection is fast; as fast as an ethernet connection believe it or not. No drops in connection whatsoever. Just thought I'd post for anyone interested in comparisons among some of the popular routers.

What I've found is that the top speed of the wireless Pre-N connection is generally comparable to the top speed of the atheros "super g" connections when both are measured circumstances that are ideal for their respective setups. My "super g" setup had been with a DLink di-624 C2 router matched up with dwl-g650 and dwl-g520 wireless network adapters. On the few occasions when the conditions were "just right", I had a superb and very fast connection with that setup. DLink's "super g" is the same technology (from Atheros) that you experienced when using the Netgear WGT624.

The issue with the Atheros technology, as implemented in Dlink and Netgear products, seems to be that it is extremely finicky, extremely sensitive to outside interference (other routers and AP's, 2.4 ghz phones, etc) and the range is nothing spectacular. For example: in order to get good throughput (3 rooms away, through 3 walls and a variety of obstructions), I had to add a 6 dBi Hawking omnidirectional antenna to the DLink router, and a 6 dBi Hawking directional antenna to the remote pc using the DLink dwl-g520 "super g" pc card. Then - SOMETIMES - if all other AP's in my neighborhood were quiet, and if all the other factors (90% unknown) happened to be just right - I was able to get a solid and very fast wireless connection.

But - similar to your experience with Netgear, I found that the DLink connection was flakey. Throughput would be up, down, connected, disconnected, etc. Other problems I encountered seemed, finally, to be related to the router degrading over time despite an enormous expenditure of time and effort to get the whole thing working.

The really significant differences I'm seeing with the Belkin Pre-N equipment are:
- totally solid, stable, connection - it has NOT gone down, or wavered, since I installed in about 10 weeks ago - period.

- range (with a pre-n adapter in the remote pc) is awesome, and accomplishing this did NOT require use of ANY add-on antennas on either the router or the remote pc.

- throughput at this extended range is tremendous.

When Belkin makes claims that throughput could be 8x that of standard 802.11g and some people criticize that, what many people seem to miss is that this claim is, actually, perfectly valid - at long range. For example: the Atheros Super G router (dlink and netgear) may be quite fast under perfect conditions, over a 20ft range -- but the speed (and stability) drop off dramatically as the distance is increased. At 80ft, you might see the throughput drop to 1 mbps or 2 mbps (for example). However with a Pre-N setup, you'll find that you can still be pumping out a true 30 mbps or better over 100 ft away. THAT is the kind of difference that makes the Belkin Pre-N equipment shine.

As you mentioned --- using the Pre-N card in the remote pc will make the difference. The card, like the router, has 3 antennas (I saw a photo and writeup online in which somebody opened up the card), and uses MIMO technology to let it pick up and disciminate weak signals far better than a standard wireless NIC can. Combined with the Pre-N router, you'll have better range than you would with a standard 802.11g card.

I too share the same problem with the same Netgear model. The 54MB before it was solid. This 108MB WGU624 seems to lockup and need to be power cycled to restore internet to the clients.

Anyone looked at this one?
SMC2804WBRP-G - Barricade g High-Powered 2.4GHz 54Mbps Wireless Broadband Router with USB Print Server
Provides up to 200mW of wireless output power for better wireless range and performance over standard powered Routers.

I like the better wireless range. Can anyone confirm this?

I needed a print server for one customer and a wireless print server for another. This should fit both bills and it is $54.95 where the Netgear WGU624 is $99.95 with no print server.

I am shopping for an AP solution for a Dr's office, and this sounds like it may work nicely. Anybody heard any news about Belkin adding Access Point functionality to the F5D8230-4 router? Also, the application I am trying to provide access to requires a CONSTANT connection. Anybody tried running any Pervasive Apps over a Pre-N WIFI connection? Also, I noticed a couple of posts claiming that the range of this unit seemed to be greater than a B or G router when using B clients. Does anybody have any +/- input about the F5D8230-4's range with G clients over a G router/access point with G clients?

The Pre-N works fine as an access point.
Simply attach the router by cat5 to any computer...
install the software cd.....
browse to 192.168.2.1
go to "use as access point"
check the box....
set your new ip if you need to match an existing network...
and then plug it into your router or switch.

should be easy....good luck.

Hi all. I'm new to the wireless game. The main reason I'm trying out wireless is because my cable provider keeps telling me to have the cable modem on a closer connection to the outlet. So I finally did it with a F5D7231 2 days ago. However the results were very dissapointing. Not only was my signal weak jumping from 46-73% but the connection always dropped when my sister used her cordless phone. So I returned the router yesterday, and picked up the Pre-N model.

The setting up took around an hour and a half, mainly because the reset button doesn't work. The reason I complain about this is because I prefer a static IP network. However setting up the router to static caused the connection to the router to never really connect and keep dropping. After some work I managed to finally get the card and the router synched. Early this morning when I first set up the router the signal was was being skeptical. Now I get a signal of 90-92%. The true test will come up when my older sister wakes up and uses her phone.

Also I am not using a Pre-N card. I am using the F5D7000 card. I'm not looking for speed at the moment. I just want stability. And if I can get the 10mbps/1mbps out of my Cable modem, I'm happy. Besides I'm use to 10mbps networks from my LAN party days.

Well after some time with the router, still having a bit of trouble with it but I think it might be the F5D7000 card. I've had some recent lockups in the last few days and the PCI card doesn't fully go into the PCI slot, the end closer to the outside port seems to stick out a little, should I change cards? Maybe try a USB wireless card? Any suggestions? I don't think my case is screwed up, my video card fits perfectly.

Well I tried buying a different card and didn't get much success. I'm throwing in the towel. Sorry everyone. I really was hoping that I could get a wireless network going with what I heard about the Pre-N router. I guess I was wrong, must be a lot of interference where I am. I will be returning the Pre-N and network cards back to CompUSA and go back to my old setup. Good luck to anyone else who tries out the Pre-N router. Maybe when N hardware is out I'll try again. Until then back to hardwire setup.

In case anyone else is confused as I was by postings on this group, I have been informed by Belkin support that using a pre-N card along with the pre-N router does NOT increase range, but should increase speed at max. range.

I do not know for sure whether this is the whole story, but it is supported by my own experience. I am now getting equivalent or better range from my laptop with standard 54g card than with another machine equipped with the pre-N card. The laptop is at least as good at maintaining the signal, as well. Perhaps this is all due to a better built-in antenna.

Sounds like the Belkin support person you spoke with might have been a bit mixed up, or explained the situation poorly.

In general, as the distance spanned increases, WiFi signal strength drops, signal/noise ratio deteriorates, and throughput drops. Also, with most WiFi devices, connectivity stability deteriorates as well -- experienced by frequent drops and (possibly) reconnects. At some point, of course, you're disconnected more than you're connected, or simply cannot connect at all.

With a Pre-N device at each end of the connection, you get much better effective range for the same signal strength, especially in an area that has obstacles and/or reflecting surfaces. MIMO technology sends multiple signals over multiple antennas and receives these at the other end. The slight difference in the signals, along with the "multipath" issues that might be cause by such things as phase differences, differences in reflected path, etc, is processed on the fly by a digital signal processor that uses this unique "signature" to pick the intended composite signal out of the overall "noise" in the same RF spectrum.

What this means is that Pre-N actually will give you better range and coverage than standard 802.11g, as well as far better throughput at any kind of distance. If you read some of the tests on Tom's Networking, ZDNet or CNET you'll see that this is borne out by test after test.

In my experience:
- range using all Pre-N equipment is improved, along with throughput and stability
- range using a Pre-N router and a DLink 54g card is also far better than when using a DLink router (di-624) and the Dlink 54G card (even when the DLink setup was using "super g").
