Anyone else having issues with T-mobile @home service?

Well as of friday my T-mobile at home service is down.. Spent an hour online with T-mobile support, then 35min on the phone with them just to tell me that my ISP is the problem. I do not understand the phone worked flawlessly for two months prior to friday.. I think it is the router, but I have been threw all the settings and the wireless works great just does not recognize the sim card, and T-mobile says the sim is good.. I am about to pick up another router, but would like some wisdom from you guys first.. Thanks in advance..

Well Its fixed.. I got a new router off ebay and swapped it out and its working all better now. I guess the linksys router they use is junk by all the used ones on the bay...

Believe it or not, about 90% of my internet issues that I've had were router related. Either the router died, or something happened to the configuration, or other. For whatever reason sometimes they just can't take the stress, some require constant reboots, and some work just fine. For most part I've had good success with Netgear, but I know tons of people that would say otherwise.
