C7800 - Cannot connect to 2.4Ghz anymore.
Firmware Version V6.01.07 So this is super annoying. I cannot connect to the 2.4ghz wifi anymore with my phone. 5ghz works fine. A lot of devices are still connected to 2.4 but I just canno...
Multiple. Phone won't connect, echos say invalid password. But yet there's probably 20 other devices connected..
Are you using any special characters/spaces in the password or ssid?
If so, change it.
Also, try setting your speed on the 2.4ghz from 1000mbps down a notch.
- No special characters. It's the same password it's been since I got the modem. I'll try that but the speed always worked fine..works once after a reboot then never again will it reconnect.
Tried lowering the speed to 433. Worked once. After I disconnected and reconneced couldn't authenticate connection.
Try changing it to something with no spaces.
Avoid spaces/special characters in the password as well
- I think I figured out what's happening. I found in another thread that Netgear gives no fs about bugs. Apparently you can't connect more than 20 devices to 2.4 and this starts happening and they never fixed it. I connected a few of my smart home devices to my wifi extender instead and I'm able to connect now. It utterly blows my mind that this has not been fixed.
One reason it may not be fix is that there maybe a HW limitation on how many devices you can connect to one radio at a time. You can't just connect unlimited amounts of devices to one WiFi radio. There are some limtations. Not all wifi can handle large qualities of devices. Been like this for years. Nature of the beast.
One thing you might do is connect a wifi extender, like you did, this helps off load some of the wifi devices to a different wifi source to share the band width.
- There's a hard limit but it's not 20. It's supposed to be supposed to be 32 per band..
Also depends on what your devices are doing as well. One device doesn't just take up 1 connection, there are many per device.
