I have a WRT45G and since yesterday, I have lost wireless connectivity. While debugging I found that the router can ping its external IP address, but can not reach its gateway. Any suggestions on what could be wrong. The only changes that I made to router around one month back was Firmware upgrade to 4.x.x, as I was trying to configure my Wii to use the router.
How is your router connected to the internet? Your gateway is either your modem or at your ISP, so not being able to reach those usually trace the problem to your ISP and not your side. A quick verification is to reboot both your momdem and your router and see. If you still cannot get connectivity, the problem is probably at your provider. Give them 24h and it should come back...
