Hello, my wifi suddenly stopped working when the latop is plugged in. It was originally set to Dual Band 802.11 a/b/g. Worked fine for weeks. Then suddenly stopped working and its saying gateway not available. After hours of trying to figure things out, i realized it only works on 2.4 ghz 802.11 g. This is only going on at my office. Here is whats going on.
Router Type: Verizon Fios. it says its dual band 2.4 ghz and 5 ghz, however the wify shows only one single name like Frontier 5623. On the router it says it should show two networks, Frontier 5623_2G and Frontier 5623_5G. Im not sure if that has something to do with it.
Please let me know if you can think of anything.
- Works fine on Dual band if on battery power. The second I plug it in, its connected to the wifi still but no access to internet.
- When plugged in only works only on 2.4 ghz. When its not working, I switch AC to 2.4 ghz and internet comes back.
- Works fine as it should on my home wifi, both 5g, 2g and dual band.
- Works fine as it should when connected to hotspot
- Works fine on all other wifi networks.
- Reinstalled drivers
- Updated drivers
- Rolled back drivers
- Reset wifi adapter
- Uninstalled wifi adapter and did clean reinstall
- Ran troubleshooting in windows 10, says default gateway not available.
