Re: [LUG] tomato/linksys router

I am running a linksys router as a wireless client. It has been flashed with a piece of software called tomato which means it can receive a wifi signal and then output it via cable to my PC. This is the method that gives me the best connection with the wifi box downstairs.

All has been working well for yonks until last Monday when we switched ISP. I set the o2 box to be setup as close to the previous setup as I could. Switched WPA passwords and while I couldn't seem to switch the IP address from and the DNS range from 192.168.1..... I was able to add as an alternate address and - as an alternate DNS range. This seemed to work fine for everything on the LAN including the linksys.

However the linksys appeared to suddenly stop working. No longer picking up a lease from the first router. Thinking this was down to the IP issues I replaced the o2 router with the previous one, substituting the log in details for the new ones. It works fine, but still no joy with the linksys router. The linksys is just not picking anything up from the main router, for example it used to have a LAN ID of, while having an address of and assiging the PC something in the 193.168.1.x range.

I'm assuming you've typo'd 193 for 192 here - it's just that you've done it twice.. (And you have DNS above which I presume is really supposed to be DHCP)

Are you sure it's nothing as simple as a harware failure of the Linksys box?

If you're sure it's OK, I'd suggest starting from scratch. Factory reset the O2 router and get it working and online. Don't bother with alternative IP address ranges in it at all, just leave it to Make sure you can access it wired and wirelessly. Also make sure the Wi-Fi channel is in the range 1-11 to start with.

Unless you really need it, my thoughts are that running 2 IP address ranges will serve only to confuse you.

Then factory reset the tomato box, connect a PC/Laptop up to it and go through the motions of giving it a fixed IP address (I suggest if the O2 box is .254), turning off it's own DHCP, etc. and put it back into client-bridge mode.

Then see if you can get an IP address on a wired PC/Laptop (wired to the Linksys), then wireless.

The DHCP server does need to be running something that responds to version 3 of the protocol to give IP addresses to devices behind a Wi-Fi bridge, but that's been out for at least 8 years now, so I'd hope it was OK there. (It's to do with multiple IP addresses behind the same MAC address on the Wi-Fi bridge unit - something we run up against in the days of the Buckfastleigh project, but ISC's DHCP hat just been updated to cover that - fortunately!) However I suspect you're OK there.

Good luck!
