two routers on network; wifi speed through 2nd router significantly slower

    I'm at my brother's home which has two linksys wrt54gl routers w/ tomato installed on his network that are connected via wire. the speeds of wifi clients connected to the second router are significantly slower than wifi clients connected to the first router and even wired clients connected to the second router. Eg. wired clients on the second router complete speedtest w/ 28M down/5MB up. Wifi clients on the second router complete speedtest @ 5MB down/5MB up. Wifi clients connected to the first router have similar speeds as hard-wired clients. What is amiss?

    The network topology is as follows:

    cable modem ---> tomato #1 ---WIRED--> tomato #2

    tomato#1 hosts wifi clients and connected via one of the ethernet ports is tomato #2
    tomato#2 connects to tomato #1 via wire that connects to one of the 4 ethernet ports (not the WAN port). tomato #2 hosts wifi clients and wired clients. tomato #2 has WAN port and dhcp disabled, its default gateway is set to tomato #1. QOS is not enabled at all on any router. wifi on both routers are set to G-only and access point.

    My first guess would be interference; try a different channel.

    i've checked that and placed them on two different channels that were also devoid of any other neighboring wifi networks. however, speeds still remain slower on the second router. it just seems so unusual that wifi speeds via the second would be significantly slower and i can't seem to identify the issue.

    I have a similar setup with no such issues. Have you tried swapping the routers?

    unfortunately, i no longer have physical access to his routers and my brother isn't one to fiddle around with that stuff. what i've done is advised him to use the wireless network/ssid of the primary router. my brother and his family don't download very much and so they never even noticed the slower speeds in the first place. i only noticed it while i was there visiting and downloading some large files. it's a serviceable workaround as the first router gets decent coverage in most areas of his house. it's just baffling and vexing for me as i set up their networking and couldn't understand the inconsistencies. thanks for all the help anyway!
