I have been experiencing a weird behavior regarding my home network setup that started about 3 days ago. I have a this particular setup for over a year now and never had any problems.
My main router is a SMC7004VBR Barricade that is connected with my PC with Vista Home Premium and a D-Link DIR-628 Wireless router.
Whenever I unplug the WAN connection in my SMC router, I am able to log into both routers. But as soon as I connect the cable from my DSL-modem to the SMC WAN port, not only do I not get any access to the internet but I can't even login to my routers anymore.
I have tried changing the cable between the modem and the SMC router to no avail. I tried doing a reset on the SMC router but no luck there either. The only way I can get internet access is if I directly plug my PC into the modem.
I also tried to do a system restore to about a week ago thinking that a Windows update might be the culprit. But I still get no access to the internet via my home network.
Now I do not have a wireless connection available plus I have no barrier between the internet and my PC.
Can somebody point me in the right direction on where to look or what might be the cause of this behavior?
Thanks in advance!
