story category DD-WRT on the v5 WRT54G
Looks like it can use third party firmware after all
(old news - 09:12AM Wednesday Apr 05 2006)
tags: wireless · hardware
The latest (v5) version of the popular Linksys WRT54G hasn't met user expectations. Not only is it no longer open source (previously preventing third part firmware), it has half the physical memory, and many users complained about the unit's performance. Hobbyists were nudged toward the more expensive Linux based WRT54GL. If you perhaps purchased a v5 version of the WRT54G, Linksysinfo reports they've found away to stuff the DD-WRT custom firmware into the device all the same.

Nice!

That's awesome they can do that, now those routers can actually do something...but hopefully Linksys won't come down on them with lawsuits and what not.

Re: Nice!

This router is still useless for the money Linksys charges for it. I say, go search for a WRT54GS rev 1 to rev 2.1 or at worse 3.0 and enjoy 8meg of flash space instead of 2 and 32 meg of ram instead of 8 !

You mind find some still in stores somewhere or just look on ebay instead

Agreed...it's still a piece of junk, but at least those that are stuck with it can actually do something with it.

I have rev 2 using DDRT firmware. If i didnt need the static DHCP i would go back to the linksys firmware, i constantly have to restart the router 2 times a day because for some reason my internet connection chokes up and gets really slow most of the time. I use BT and Usenet and before with the linksys firmware it worked fine. But now after a few hours my connection gets really bad with this firmware.

Re: Nice!

I doubt you would have better luck with the original firmware. Even the best linky's only had 32MB of RAM - and when you are using protocols like BitTorrent, where you are making connections to many different machines quickly, it doesn't take long before the connection table gets full.

It would help if EITHER firmware would do a better job of garbage collection, but alas - they both wait too long to clean up their ARP tables. The end result is that the machines bog down when you start connecting to a large number of unique hosts rapidly. The same thing will happen if you surf a lot of different sites in a short period of time as well, though it takes a lot longer - since you are presumably reading the web site, adding a delay. Note, if you can kill the ad servers with adblock, or a ad-blocking proxy, you can cut way down on the number of unique connections. Some websites will link to as many as a dozen ad servers or more.

Unfortunately, BT is a true "broadband" application, and most consumer routers have a hard time keeping up. My old (retired) Netgear router used to suffer the same problem as the Linksys routers. Eventually, they would run out of memory and slow way down (though the RT314 never did crash out on me)

This is one reason why I built a FreeBSD based router with 256MB of RAM. That machine has sat quietly in a closet routing non-stop for over 4 years now. Only power outages lasting more than 2 hours disturb its up-time - and its throughput hasn't decreased noticeably in all that time.

maybe if someone found a way to hack more ram into the wrt54gs, then the issue of connection tables due to bt'ing would go away... i wonder what the total addressable memory of the gs really is...

I'm guessing because it's a rev.2, you've had the WRT54G for a while. Have you tried a more recent version of the Linksys or DD-WRT firmware?

If you're using P2P, that's a FAQ. Here is a link to useful suggestions, from the WIKI:

»wrt-wiki.bsr-clan.de/index.php?t···Slowdown

Any more followup, post to the proper fora.
They are also close to releasing v23 SP1. SP1 has alot of fixes over the original v23... and you may even have installed v22 on your box. You can try a beta now.

Dude,

You will thank me for this advice. The default max # of ports is set too low for P2P. I had the exact same problem. Increase the max # of ports setting to 4096 and change the expiry time to 900s. It works INCREDIBLY well after you do that. Best firmware I have EVER used with that router doing a LOT of p2p. Best firmware period IMHO!!

Thats nice. though that doesn't change the fact that these routers are neutered with half the physical ram of the older models.

What about the WRT55AG?
Seems that every other router out there has a hacked firmware for it but this one.

WRT54GL

What about the WRT54GL? Isn't that supposed to have gone back to open source capability? More memory, runs on Linux, and is wide open. Any thoughts?

It's only available online and it seems to come and go... with rumors back and forth whether it is or isn't going to be discontinued. It is also more expensive without all the deals that the plain WRT54G has...
