C2300 5Ghz problems after firmware upgrade
Model:
Archer C2300
Hardware Version: V1
Firmware Version: 2.0.3 Build 20180611 Rel. 77668(5553/5553)
I bought this router yesterday and it worked fine. The Admin Portal instructed me to upgrade firmware, so I did, to the latest version available.
Now the 5Ghz network barely works. 2.4Ghz is OK
Symptoms are:
- High packetloss for connected devices (95% packetloss)
- Any packets that do work, are high latency - eg up to 4000ms
- The same devices exhibit no issues when connected on 2.4Ghz
- My previous router works fine in the same area on 5Ghz, proving there are no environmental or interference issues
- The issue occurs after channel changes, Transmit power changes, and changing other settings eg MIMO
- Devices usually cannot connect at all - with a report of "Bad password" even though the password is correct
The device has been factory reset to the beginning. I am using the default factory wifi settings and the issue still exists.
Does anyone have any suggestions?
