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.
Hi devlishro,
I think this is not an issue with the router but the limitation of your older devices. Your devices will only work when the router is forced to operate to only G mode which is at 54Mbps.

Hi devlishro
To verify, when the 20/40Mhz coexistence is unchecked, the device cannot detect the 2.4Ghz of the router but if it is checked the computer detects the 2.4GHz. Am i correct?
Hi James,
Sort of, the checkbox sometimes doesn't display correctly if the 20/40 Mhz is enabled or not. I was able to connect after clicking save multiple times with the checkbox unchecked as well.Did you update the firmware? If so did you do a hard reset after before entering your settings manually not using a backup? Leave WMM on as default, leave 20/40Mhz as it is checked also don't turn on HT160 as noted in the latest firmware notes "Intel 7260/3160 has a connection problem with the R7800 when the HT160 is enabled. This issue is due to the Intel driver. Intel is looking into this."
