Archer T4U: how do you change the 5GHz band region?
Hi,
My laptop built-in wifi card died while I was on business trip to South Korea.
To ensure good compatibility and support, I specifically purchased a TP-Link product which is sold worldwide:
- Archer T4U AC1300 MU-MIMO
- Version 3.0 (shown next to the S/N)
- Windows 10 version 1909, driver version: 1030.22.202.2018
I am now in Europe and realized that this adapter does not see some 5GHz networks because it seems restricted to the Korean authorized bands.
The funny points of the story:
1-There is no such thing as "Korean" driver. It is the same driver as the European or US version. I checked all the local TP-Link websites accordingly.
2-The TP-Link adapter is duly 'CE' certified along with additional 'FCC' and 'EAC' markings. Clearly not a product developped specifically for a local market, the very reason for which I purchased it.
3-There is no option in the adapter driver advanced properties to change the 5GHz region as for other TP-Link USB adapters.
4-I changed the region of my Windows 10 to different Euopean countries but to no avail
5-I reinstalled the TP-Link driver from scratch several times to "trigger" identification of my location. No success either.
6-I changed the 'Wireless Mode' in the adapter options (auto, ac only, a / n / ac, etc..) but this did not help.
At the moment, I rely on my luck that the wifi router I am allowed to connect (e.g. hotel, 3rd party company,...) is in the 5Ghz bands authorized in Korea.
Question:
How do I change the parameters of my Archer T4U to comply with the European 5GHz bands?
Many thanks in advance,
Mike
