    Dear networking experts:

    I have a simple routing question. It will be highly appreciated if someone here can shed some light on this:

    I have tow wireless routers. Main router (Linksys WRT54GS v6) connected to internet modem. Original Linksys firmware. 2nd router (Linksys WRT54GL, tomato firmware) served as a wireless client (2 PCs connected to it). I have WRT54GL ip at, subnet Had DHCP server turned on, ip ranges from - The two PCs connected to the WRT54GL router can surf the internet without any problem. However, I have a printer connected to one PC connected to the main router, hence, ip in the - The problem I am having is that, the two PCs connected to the 2nd router cannot connect to PC on the main router by name (can only connect by ip, not name). Is there a way to fix this?

    I believe that is by design, as when you want connectivity via name you generate alot of broadcast traffic and the route as you have discovered is limiting that across the wireless link. If you were to put the host (printer) machine on the same physical lan it would work as the broadcast lan traffic is expected and passed to all hosts.

    Hi, ifican,

    Thanks for the reply!

    Before I got the WRT54GL, I had a XyXEL wireless router. This is was setup as wireless client and the two PCs (now connected to WRT54GL). On the ZyXEL wireless router, I had it on the same subnet as the main router, ie, I had no problem connecting the printer by name.

    On the WRT54GL router, when I set it to the same subnet, while keeping all other settings (, then, it failed to connect to the main router. Maybe,in the case, I cannot have two routers functioning as DHCP server and at the same subnet (althought, the range of IPs they are giving out are different).

    No, you should not have more than one DHCP server on your network. When your network is properly configured, all clients should be able to get a DHCP IP from the one DHCP server. This should cure your host lookup problems.

    Thanks J.M.!

    In another tread, RonWessels clarified the differences between wireliess client mode vs WET. For this to work, I have to switch to WET mode and put everybody on the same subnet and only 1 DHCP server.
