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.
