The WiFi problem has been persistent for a long time, affecting my daily life.
In short, a year ago our ISP replaced our modem with one featuring Wi-Fi and 5GHz networking. From the start, connecting via my PC using the TP LINK AC600 T2U Wi-Fi dongle was problematic. This issue has remained consistent after every uninstallation and factory reset of the modem. I've tried various workarounds, such as adjusting the PC settings to allow connection, but it still doesn't resolve the problem. Now I notice that recently I'm connecting to a 2.4GHz network instead of the 5GHz one I usually use. It seems the connection was interrupted and then re-established. The adapter sometimes disables itself when trying to connect to 5GHz, showing it can't reach the network. I've been searching for a permanent fix on my own, but haven't found a lasting solution. Using 5GHz would be ideal since it offers much faster speeds—up to 20 or 30 Mbps—and is significantly better overall. Please help me find a way to get this working.
I can verify the Wi-Fi adapter on another device. Please confirm if it works there. If not, we can obtain a new one or proceed with troubleshooting.
No I can't,but there is no reason that it should be dying,since I can connect to 2.4 pretty easily and it works just as good as it worked the first day I started using this wifi dongle.This consists only on the 5GHZ connection and I have pretty much ran out of solutions. If you guys are familiar with the UPC Connect Box.
Thats why we recommended another dongle. Since no other solutions. But yes those devices can stop working after time, there is ABSOLUTLY no reason that if it worked before that it would keep working. But yes it can easily be that the 5Ghz part is somewhat broken and the 2,4 Ghz still works ok. And the downside with networking is there are so many variables... Thus the only way to be sure is to check it on/with other hardware.
The router is guiding you toward 2.4GHz because it thinks the connection is weak (higher frequency helps farther). A weaker 5GHz link will feel slower than 2.4GHz under average signal strength. You might turn off the 2.4GHz channel on your router... Or if you're on Windows, open Device Manager, locate your wireless adapter, double-click it, then go to Advanced settings—often there’s an option to disable 2.4GHz on the dongle.
I attempted that with my friend. I tried using only 5GHz on the adapter, but it only detected 5GHz connections. Still, I couldn’t connect, and the 2.4GHz connection from my TP-Link old router isn’t working either. If I turn off the 2.4GHz, I won’t be able to access the internet at all.
To determine if 5GHz is optimal for your needs, test actual speeds with a direct connection. If you're near enough, use a wired link; if not, 5GHz won't improve performance. The specific errors you encounter when connecting to a 5GHz network can indicate coverage issues or interference.
My computer is in another room, so I’d need to drill a hole into the wall to reach the cable and use a longer one. I’m sure 5GHz will perform much better since Discord doesn’t experience constant high ping. Right now I’m getting around 20-30mb/s on 5GHz while on 2.4 it’s barely over 2mb/s, and my YouTube videos are very choppy. I know exactly why I prefer 5GHz—no errors when typing passwords, just a brief 10-second pause before the connection drops and then it turns off and back on with a warning. My old PC still works fine with a little optimization, but its cable speed is only 500mbits, while my PC can reach 100mb.
