    Does anyone know how to set the WRT54GS DHCP Range to something other than 192.168.1.x? Due to corporate edict, I need to use a range more like 192.168.51.x, but it seems like the first 3 digits are fixed, even with the latest Linksys firmware. :?:

    You have to change the router's IP to something in the new subnet first. Then you can change the DHCP to match. So change the router to

    Many thanks - I'll try that tonight. On a separate note, a friend is having some range problems with this unit, so based on the advice in this forum I'll advise him to try a directional antenna on the remote nodes and perhaps HyperWRT with a higher transmit power.

    You may also want to change the wifi channel; specially if you have 2.4Ghz cordless phones. I have 2 different units, one for my landline, and one connected to my VoIP phone. EWireless connection was a nightmare, frequent dsisconnects, I Changed wifi chanel on the 54gs to 1 from 6 and it seems to be OK now.

    Wireless Range with WRT54GS

    I use Panasonic 5.8 GHz cordless phones (great!), so there is no interference (I leave the WRT54GS at channel 6). By changing from mixed mode to G only, the signal strength at 70 feet increased from 7% to 20%, which works well enough for 390 KBytes/sec downloads through my cable modem and reasonably responsive web browsing. This is with the internal antenna of a Linksys PCMCIA card on a laptop.

    I was wondering if you ever resolved you problem with the changing of the internal ip from something other than 192.168.1.x. I am having the same problem and I tried to change the local IP address to but when I did this my network went down and I could not access the router. I then had to restart the router to get access to it again. Any suggestions are greatly appreciated.

    once you move the router to a different subnet your computer has to be on the same subnet for it to work, you'll either need to restart the router and your computer should grab a new ip or restart the computer then you should be assigned an ip on that subnet and should be able to login to the router at the new ip...you won't be able to get back into it until you do this though...(you can also manuially release and renew)

    Are you going to use private or public IP addresses in your network?

    I think it is more secure to use private IP addresses as they won't be broadcasted to the internet. If you do Google, you will find a lot of advices in setting up IP network.

    To me it is clear that when you changed your router IP address, your network went down. This is mainly due to all other computers were still in the same subnet you used before which is different from the one your router is currently using. Did you change the subnet mask in the router accordingly? Below is one of the tools to define network IP addresses.


    I changed the subnet in my private network several times at beginning. And all computers (just 4 though) were automatically re-newed, their IP addresses.

    I use class C range of IP addresses ( - in my private network, with netbits of /29 as I just want to have not more than 6 hosts in my 2 subnets accessing one WRT54GS.

    I am not sure though if we could use class A or B IP addresses in for instance WRT54GS as I have never tried that. But who would use thousands of hosts in one WRT54GS?
