Nighthawk R7800 - Old wifi card can't see 2.4 Ghz
Hello everyone, I recently had to return a router because one of my laptops was not able to see the Router on the 2.4Ghz network. Network card: A 802.11n Wireless LAN Card from Ralink Technolog...
Hello NetGear TM,
I have ordered the same router again and the problem is still there.
Except this time I played with it a bit more. The UserInterface or the settings of the router are not being displayed/applied properly.
More specifically the 20/40 Mhz cohabitation checkbox appears to be having this issue. Unchecking/Checking the checkbox and applying the settings several times can reproduce and fix the problem. My laptop was able to see the 2.4 Ghz network with both the 20/40 Mhz checked and unchecked. I am guessing the interface doesn't always apply the 20/40 Mhz cohabitation setting when you click apply - although if you refresh the page the checkbox is enabled.
To anyone else experiencing this problem: for the 20/40 Mhz checkbox - try to uncheck it - apply settings, check it apply settings several times until your wifi card will see the network.
Speeds are downward compatible. Set it to max speed. Did you enable WMM? What's idea of updating f/w for trouble - shooting anything? You trouble-shoot problems without changing anything until you have reached a solid cnclusion f/w is causing the problem. Then update f/w. Did card hae latest driver?
