I've had this linksys e1200 router for about 6 months, and it has always worked fine. But last night it stopped having internet access. I hadn't updated windows or changed any networking settings recently, so I don't really know where to begin to track down what's wrong.
I do have internet access by plugging directly into the modem (my current configuration, to allow me to post here). Going through the router, however, neither the wired nor the wireless access works. My computer can see the wireless network at "full bars" but it says "no internet access". When I'm connected to the wired internet through the router, I can ping the router (192.168.1.1) but not outside servers (eg 8.8.8.8). I can also ping the router via the wireless (i.e. when I am only connected to the router wirelessly, and not through the wired connection). So it seems that the internet/modem is working fine, and the wireless signal is fine, but the router doesn't want to talk to the modem properly??
Below is what I get from IPCONFIG /ALL while wired through the router, but I'm about at my computer literacy limit, so I don't really know what to look for and nothing really jumps out at me. Is it odd that the DNS server for the Ethernet adapter LAN is the router's ip address?
I'd really appreciate any help or suggestions you have to offer.
(n.b. I'm mainly working on a thinkPad t430s with windows 7, but have machines with XP and Ubuntu 12.04 also handy if that makes any troubleshooting easier)
