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?
As mentioned, the only way to get it to work was to set the router work with 54Mb/s. Setting it to the maximum speed would not allow the WiFi Card to detect the SSID.
Could not find better drivers than the ones currently installed by Windows 10.
You speak about troubleshooting without updating firmware. Well considering that newer firmwares are usually packed with fixes, you could see how I was hoping for a newer firmware to have covered the issue I was experiencing. I do not see any advantage to not updating the firmware. The firmware is also a driver to the router if you will, and then you recommend updating the wifi card driver but not the router's driver - your ideas conflict themselves.
Also can not see why WMM would enable the wifi card to detect the network or not as it is probably an issue as you said of backward compatibility.So did you enable WMM or not? Did the releaser note of the firmware address your problem?
Did you even read it? Nothing wrong with R7800 which is a good router. I am using one myself.
