Now on my 3rd WAG54G after first 2 RMA to Linksys after dying and this one is doing the same a slow slow death, wireless disappears, router wont establish new routes, web front end goes away !!!! Anyway spent ages to Linksys support about getting port forwarding working and other issues and their advice was:- - Single address port forwarding may require the router to be power cycled after having set up. But blooming unhelpful when router is at a remote unmanned site !!! - With single address port forwarding the external and internal ports have to be the same, contrary to what the web front end and user manual state/allow. - After performing remote management router may be unreliable/unresponsive and require to be power cycled to get working !!! Anyway this one is being returned as "unfit" for purpose (ie port forwarding and reliability) and a Netgear DG834G and WG511 card is being fitted as a replacement and after a week has just worked 100%. OK DG834G only does port range forwarding BUT AT LEAST IT WORKS !!!! As an aside (to prove it is not my setup) I have been running a WRT54G and Zoom ADSL modem for two weeks now and not had one connecticity, speed, reliabilty issue, port forwarding problem, line drop or anything else what so ever, all just worked 100% as I would have expected my WAG54G to do !!! Wireless is 54Mb all over the remote site unlike the WAG54G whose signal strenght varied considerably and would just get slower and slower and disappear until WAG54G powercyled. I have sat with a portable right next to a WAG54G and watched the signal strength slowly (5 minutes or less) go to zero, rate get slower and portable just disconnect. Power cycle WAG54G and all is OK until next time.
