I have installed a Vigor 2925N in my house, but i have problem with wifi of my access point TP-LINK.

I can connect to SSID of my access point but when i try a speed test, upload is 0. I don't have problem in download, only in upload i have 0 MB/s.

If i remove the Vigor, the wifi work correct (download and upload), when i connect draytek upload return to 0.

- I tried to disabled firewall in the options
- I tried to reboot with factory default and riconfigure the device
- I tried to update firmware
- I tried to change Vigor with the same
- I tried to change Vigor with 2926
- I tried to change access point with another 4/5 device
- I tried to change patch

but i cant resolve this big problem. I must use the wifi of access point with the Vigor in the same network.



This is a map of my network:
Internet --> Draytek Vigor 2925N --> Access Point --> Smartphone/computer (upload 0 MB/s)
