I have a WRT54G V4 that I flashed with DD-WRT v24-sp2 (07/21/09) std (SVN revision 12533) a long time ago. The performance was adequate when I was on DSL service as the phone lines were the bottleneck. Now I'm on cable and measured over 300 Mbps DL hard-wiring off the modem but only get like 40 Mbps and 18 Mbps DL speed for wired and WiFi out of the WRT54G, respectively.

My questions are:

1. Can I hope to gain significant speed boost by trying different builds? I would like to at least reach the 54 Mbps that the "54" in WRT54G stood for, at least as advertised by Linksys.

2. Am I on the wrong track and should look to a newer model router? My needs are modest, having lived with DSL for a long time, and also see that others are using routers of similar vintage.

Thanks for your input.

https://wikidevi.wi-cat.ru/Linksys_WRT54G_v4.0 CPU Broadcom BCM5352E 200 MHz, FLA 4 MiB, RAM 16 MiB

Recommended: R7800 (XR450/XR500), R7500v2, EA8500 (serial flash), R9000 (R8900/XR700), x86 (J4125).

Welcome to our lively community.

Feel encouraged to upgrade to next public DD-WRT build after 08-20-2022-r49792, if not for anything but a myriad of known security exploits being patched.

Now speed wise: Your router has

CPU1: Broadcom BCM5352E (200 MHz)
FLA1: 4 MiB (Intel TE28F320C3BD90)
RAM1: 16 MiB (Hynix HY5DU281622ET-J)

What do you really expect here with these specs? You will not be able to turn that pushbike into a Ferrari.

Feel free to read https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=329577 and https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=325918 you will need a better router.

There are other threads talking about what router is best, feel free to search for them.

I recommend Atheros routers they are supported by opensource drivers, as opposed to Broadcom. Anything with a dual core CPU with 1200Ghz or better will be future proofing you eventual move to higher WAN speeds.

PS yep blkt beat me to the post by typing less words.

Less is more. Wink Commonly recommended is R7800 or gaming series variants XR450 (costco model) and XR500.

Honorable mentions: R7500v2 but availability is less and EA8500 if stock FW is encrypted USB to TTL serial flash.

An Archer C7 / A7 v5 would be adequate, but future proofing is definitely the best option. Of course, if we go with that mindset, just get an x86_64 supported device and set up wired APs.

Can you expand on this? I'm sorry, I only research these topics as the need arises as you can see from the age of my router. Since I will probably run the new router until its demise I'd like to futureproof as much as possible.

I have started to look into the models suggested by some of the other folks above.

Thanks.

  1. These threads should be added to Router Recommendations for High Wired Performance, What’s the best dd-wrt router to buy in 2021?, What Router or Access Point to buy for dd-wrt? or otherwise stickied / added to an announcement / sticky in the respective forum:

  2. This wiki is in need of some editing, but it's a starting point:

  3. Old, mostly irrelevant (included for posterity):
