I've got a Linksys WRT54G v5 router with the latest (1.02.8) firmware. I have two boxes running Slackware 13.1 (one is 32bit, the other 64bit). Both boxes have Linksys WMP54G wireless cards. I run an ssh daemon on both of them so I can access them to transfer files, etc. I am able to ssh from one to the other. But eventually when I try to do it, ssh will complain "no route to host." Rebooting the router immediately fixes the problem. Any idea what the problem might be? Both of them can still access the Internet, etc., even if they can't reach each other.

As an aside, transfers between the two boxes can be painfully slow--certainly no where near the theoretical maximum.

I looked at switching to DD-WRT, but the instructions seemed to be far more difficult than they would be worth. If nobody has a good solution, is there are reasonably-priced wireless router that you would recommend?

I like that particular linksys model. I'd go with X-Wrt which is a bit more user friendly (in my opinion). Basically you just go to the firmware update page of your linksys and then pick the x-wrt firmware file. Then login to the web interface and configure it how you want.

Not sure if that will fix your ssh problem though. I'd also make sure the router is cleaned out (i.e. not full of dust) and that it has plenty of room around it for ventilation. My WRT54G v1.1 tends to get hot and then needs rebooting. It'll keep functioning, but if I lose a connection for whatever reason (reboot, run out of range, etc), it won't assign a new IP. Then I have to reboot and its fine.
