Hello all,

 

I've been having serious difficulty maintaining a stable wireless connection to the university.

At random intervals, my connection will go to limited. If I run the Windows troubleshooter, it resets the Wi-Fi adapter and displays "The default gateway is not available. (fixed)" I've tried installing/updating drivers for my wireless card, resetting TCP/IP stacks, ipconfig /flushdns, uninstalling the card and reinstalling it, turning my Symantec Endpoint Protection on/off, disabling IPV6. I feel like I've exhausted my options.

Please let me know if you have any suggestions.

Seeing as you are connected to a university network, have you checked to see if other devices are having the same issue? It seems like the access point you are connecting onto may not be holding a reliable ARP table.

No one else has disconnection issues of this magnitude. I've also tried clearing arp caches on my end with no avail.

It's odd since I remain associated to the access point, I just periodically lose Internet access.

Have you checked your Event Viewer logs around the time that you get disconnected to see if there are any errors listed there?

Also with the log views, have you tried using another Wifi adpater like one you can purchase from Walmart to plug into the USB port, this would help rule out a hardware issue with your built in wifi equipment.

I have checked the event viewer. No issues are reported there.

I just ordered a dual band wireless adapter to check for issues. Thank you all for your help.
