| WRT54G?? Need objective input....or HELP!!!
Heres the problem. T1 to switch, to WRT54G for wireless office. The "wireless" just stops working for a few minutes at a time...Static IP's out of the switch are fine, and 3 office computers running off the LAN ports are fine. But the wireless just stops. I can ping the router, but cannot display a webpage.....It's driving me nutz.
If anyone has an idea, or needs more info, please reply back to the post....
Thanks

Does it do this on more than one computer that connects via the wireless?
Have you tried to update the drivers on your wireless NIC?
Have you tried to change channels on the AP? |

| The problem can last 10 seconds to as long as an hour. It has only happened 3 times in 2 years, but YES it only affects wireless as those pc's plugged into the lan ports are not affected.
I have changed out the switch, the router, and it affects all wireless pci cards, usb adapers, anything wireless.
I'm in a rural area and I have never had an interference problem of any kind. Now, remember this, the link stays, the signal strength is very good, and I can ping as far as the router, but can't pull a webpage, almost as if it is a DNS problem.
I have even swapped out rubber duckies, and hooked up an omni to see if it was an antenna problem, but it does not go away...
The only thing that stays consistant is that I can't ping through the router to the T1 when this happens, but I have also tried 3 different brand of routers. I have even bypassed the router and switch to go directly to the T1, and then the problem goes away, so it has to be either a switch or router issue. But after swapping them out with different ones, the problem starts again....
It is literally driving me nutz...

Saybrook, IL | Have you updated the firmware in the router? I had a similar problem with mine, but it never lasted that long. Just a couple of seconds, almost like the DHCP didn't work properly. Just a thought. |

Problem = Wireless Driver in the WRT54G. Update your firmware.

| Firmware Version: v3.01.3 - HyperWRT 2.0b4
Guys. As far as I know this is the latest firmware. You apparently didn't read all my post.
I have tried 3 different routers, hence 3 different firmware. I can pull an IP, therefore DHCP is functioning. I can ping the router...What I can't do is pull a webpage, or ping through the router when this happens...

| Ok guys, I came here for some objective help. I own a WISP and have for more than two years. It happens with Linksys, Netgear, D-Link, it happens with my breezenet Pro-11D AP, it happens with the 2611-CB3-PLUS.
So it's not firmware. I was hoping for some help, not sarcasm. If I hadn't tried everything possible I wouldn't have asked for help....

| Sorry, didn't mean to offend you. I know you have been here for a long time. So is it safe to say it has happened more than three times in two years? Otherwise, how have you tried all of these different products? I'm just looking for more info.
Just a note to anyone -- it really helps to give all of the info you have at the first, otherwise people start making assumptions! |

I have changed out the switch, the router, and it affects all wireless pci cards, usb adapers, anything wireless. I'm assuming that it must be happening more often than you say. Anyway, your trouble shooting is good. You have no RF interference, the problem occurs with a variety of wireless routers, and you have tried a different switch. The problem is persists through all combinations. What have you not changed ? The most obvious and most likely. Your CAT5 patch cord. One final test to try before you change the patch cord;
1 - start a ping loop -t
2 - wiggle the patch cord vigorously and look for time-outs.
3 - bang the hell out of the switch and router and look for time-outs.
4 - change the patch cord
5 - post your results here. We are dying to know what happens !  |

I have had times where DNS was having a problem, especially to »https:// sites. If I let the DHCP server (in the one I remember it was a NetGear wireless router) serve the DNS entries it would not work. I hard coded DNS in all the PCs and everything has run since. To check this, and I don't think it was in your post above, ping the address if the ping by name fails. This is a question that may help us help you, too. When you state you cannot ping through the router, is that by IP or name?
What do the lights on the WRT show? LANs show link? WAN shows link? Wireless shows activity?
Can you ping the other way, from the t1 back to a wireless device. If you need to get outside to do this, you can ping from www.dnsstuff.com, or a similar site.
Also, you list a lot of equipment that has the problem, but it has only happened 3 times in 2 years. All of these client devices attached to the router in question? If no, how did you determine they all fail?
I have never seen a network setup as you describe. How does the T1 get into a switch? I have only seen T1s into a router as a T1 is serial, not ethernet. Don't know that this has anything to do with your problem since the wired devices continue to work, but I am curious.

| You're right, I phrased that wrong. T1 to Cisco (2600 series) can't remember off hand, I think it is the 2620, to a 12 port switch, (swapped out with 5 port}. Also listed wrong Senao, the one I tested with was the 3054-CB3-DELUXE.
Right now I'm at home, I have a Netgear ME101 bridge hooked to an external antenna, running to my 3Com network card, I am getting signal. I also have a Netgear MA111 USB adapter plugged in as it has the signal meter. Signal will drop out totally til I lose connection on the MA111, yet the bridge does not lose signal, and they are spaced 2 feet apart. I went to 3 customers homes today to test their setups, all running Dlink DWL 520 pci cards to external antennas, all less than 500 feet from the 125 foot tower, with 17.5 DB Omni antenna. I got the same results, the USB would drop signal and with PCI cards wouldn't.
I checked and replaced every patch cord, as in the past two days this is happening hourly, not for very long, and no one has complained, but to me it is a symptom of a problem yet to happen...
Even sent someone up the tower to check connections and everything is fine...
I did run a throughput test during the last "outage" and the results were: Before drop
Last 24 hours Last 7 days
Number of tests 27 29
Download speed 1075.20 KBits/sec
134.40 KBytes/sec 1074.23 KBits/sec
134.28 KBytes/sec
Upload speed 787.29 KBits/sec
98.41 KBytes/sec 801.30 KBits/sec
100.16 KBytes/sec
DNS Speed 362.00 mSec 362.00 mSec
Latency 0.00 mSec 0.00 mSec
During the drop I lost about 90% of throughput....
During the drop, I can still ping the routers static IP, but I can't ping the T1's static IP, but all lights say the link is good, lan, and wan, and the activity light is blinking.
Now the weird part is, PC's plugged into the router using DHCP assigned IP's, and cat 5 ARE NOT AFFECTED. That is what is driving me nutz....
If you need anymore info, please ask, and I apologize for being huffy, but I've been up 30 hours trying to figure this out and keep it going, a hard reset seems to pull any/all routers out of the "drop"....

Re: WRT54G?? Need objective input....or HELP!!!
said by mrmuse :Guys. As far as I know this is the latest firmware. You apparently didn't read all my post. Careful ... I read all of all of your post(s).
The WRT54G running Hyperwrt is not running the latest version of the firmware. It is running third party firmware. While I prefer Sveasoft firmware for this purpose, it is hardly the "latest" firmware. Usually it is prudent to discuss Hyperwrt firmware issues with the author of the firmware, exactly as it is prudent to discuss Sveasoft firmware with the authors of that firmware. The LINKSYS forum is a great place to do that. So is linksysinfo.org.
That said, if you are indeed still talking about a problem with wireless clients not being able to connect thru a WRT54G, while wired clients are able to do that. There is only ONE place the system can be failing, the wireless subsystem in the WRT54G. Think about it for a moment and it will be clear to you.
1) The device has wired ports serviced by a driver which takes incoming data and hands it off to the Linux IP stack.
2) The device has a wireless device with a driver which takes incoming data and hands it off to the Linux IP stack.
3) Once the data is in the Linux IP stack it is treated identically by said IP stack. It is handled by exactly the same firmware and hardware after the device drivers are done with it.
These facts can be used to logically construct a rule set which can only lead to one conclusion.
1) Wired data is OK... Has no problems.
2) Wireless data is being dropped in the device.
THEREFORE the problem must be in the wireless driver or the wireless hardware itself. Since you have tried various versions of the Linux firmware for the device and since the third party firmware developers can't get the source code for the device drivers and the program used to control them ... It SHOULD be obvious that the problem is in the wireless drivers or wireless hardware.
Now if the problem can not be duplicated in the lab, you should consider RFI. |

You say that you see this with various client devices, great client devices are eliminated as the problem source. That leaves the router. Since the title of the thread suggests we are discussing a WRT54G we can get back to the basics.
Read the other post and you will have a proper answer. Next time you are tired, take time to collect your thoughts and present your question clearly. Often that helps me to solve the problem. I can't count the number of times I've spent an hour writing a question only to stroke "Upon reflection" in the past few years.

As I said before, it has happened and is still happening with 3 different routers, 1 breezenet AP, and 1 Senao AP. Two different switches, the only constant is the T1 and the Cisco 2620 router.
Even swapped out the omni, swapped out all cables...Even pulled the lightning arrestor out of the loop to see if that had an effect....
It is clear to me that the same problem is happening with completely different equipment, so how can the Linksys or the firmware in the Linksys be at fault.
I even flashed the Linksys with an older version of firmware and it continued the problem. That is what is frustrating, I've swapped out everything and it still continues.

Need objective input....or HELP!!! one could at least hope there was.
The problem you have been describing, that you loose wireless connectivity thru the WRT54G no matter what you connect it to, while wired connectivity remains has been explained.
READ my posts.
