Network communication between computers keeps dropping
I'm at the end of my rope with this one.
I have a Belkin N+ router, a laptop and a desktop, both running Windows 7. Desktop wired Ethernet, laptop connects wirelessly, via one of two wireless adapters--a Dell WLAN card, or a Netgear RangeMax adapter (I've tested this problem with both adapters, and the behavior is identical regardless which adapter I use, and I disable the one I'm not using).
When I first connect wirelessly, all is fine. I can access the other computer and its files on the network. After a matter of minutes, though (average time around 15 minutes), the laptop "disappears" from the list of DHCP clients on the router's webpage, and I can no longer "see" the other computer or access its files. This is true whether I am on the laptop trying to access the desktop or vice-versa.
I've turned off both firewalls for testing (on both computers), and it happens with them off as well as on.
I've triple-checked that the security setting (WPA2 with AES) is the same on the router and the adapter (I've also tried changing the security settings). I've tried changing the channel, I've tried putting "protect mode" on.
Even though the laptop seemingly "disappears" from the router's client list, I can access the internet just fine, and I stay connected to the network--I just can't access my other computer or its files.
Incidentally (or maybe not), I have NEVER been able to get "homegroups" to work.
I also have network discovery "on" and my network is set to "home".
I have called Belkin, whose tech support insists that if I am able to access the internet, it can't be anything in the router itself.
I believe that this is a relatively recent development, but I can't think of any settings that could have been changed. (The Homegroup situation, though, has been going on since I installed Windows 7).
Any ideas would be appreciated--I have tried everything I can think of or find online.
