Dear friends, own a GL-mt300n-v2, GL firmware updated.
I'm having dificult times with it:

*internet gets from tethered by USB Iphone
*wireguard conf file uploaded and is runing, rt, tx packages ok
*wifi is up and running, also my pc connected to wireless GLxxxxxxxx

If i do a speed test on my iphone - i get 12-14mbps
If i do a speed test from my pc, connected to GLxxxxx wifi+wireguard vpn - i get 1-5 mbps
If i do a speed test from my pc, connected to GLxxxxx wifi witout wireguard vpn - i get 12-14 mbps exactly like speedtest on iphone.

MTU for vpn connection changed to 1360

Are there chances to get a speed with vpn on closer to 12-14mbps mentioned earlier?

How about if you do speed test on your pc: connect the GLxxxx WiFi without WG VPN, run WG VPN client in the pc? This test is for check the WG VPN speed.

But given Mango hardware performance, its rate may not be too high.

These are the speedtest of Mullvad from UK and Netherlands in the Mango.

Yea, this scenario is simillar to
If i do a speed test from my pc, connected to GLxxxxx wifi+wireguard vpn - i get 1-5 mbps

The mobile internet from provider is pretty ok..12-14mbps, but as soon as wg VPN conn starts on Gl or on wg PC - it gets worse.

If you start the WG client with your VPN provider profile in the PC, there are not bottle-neck of the VPN tunnel in the Mango (as the Mango is not running the WG), the fastest speed (1-5 Mbps) is your VPN server of the service provider.
