I have a strange problem and I have exhausted my limited network troubleshooting skills. Please help.
I have a My Net N900 router with several devices attached, both wired and wireless. Everything works great until I connect my laptop device that I bring home from work. When I connect the laptop I loose internet connectivity from all of my other devices along with the laptop. I am able to see my home network but I can’t access the internet. The loss of internet connectivity occurs within 5 minutes of connecting the laptop.
In my troubleshooting efforts I have learned:
I can turn off my wireless on the laptop and connect it via the wire. I loose internet access.
I can disconnect the wire, turn on wireless, I loose internet access.
When I loose internet access, I have to disconnect the laptop and usually have to power reset the router to recover although on at least one occassion I waited for a while and it recovered on its own after disconnecting the laptop.
I booted the laptop into safe mode (Windows 7) with networking and I do not have any problems. Everything continues to have internet access.
I am convinced that there is something on my laptop when booted in normal mode which causes the symptom but I don’t know where to look. Note that the laptop is configured to a domain for connecting to my network at work and when I boot the laptop at home I logon with the computer only logon. I do not have any issues running the laptop at work.
Any advice on what I can look for?
