I have a TPLink router MR3420 v3 and a Repeater Everest EWR-523N2.

The problem is that even though the repeater connects to the router (wirelessly), when I try to connect a device to the repeater it either can't connect (if a PC) or causes the repeater to disconnect (if an Android phone) from the router.
I tested the repeater at a friend's house with another router and also with my phone in tethering mode. In both cases the repeater worked and other devices were able to connect to it.
Could it be that the repeater isn't compatible with my TPLink router?
Things I've tried on the router:


Change channel
[*]Change security type: WPA-PSK, WPA2-PSK, AES, TKIP (haven't tried WEP or no encryption)
[*]Changed mode 11bgn, 11bg
[*]Channel Width: 20 and 40 Mhz
[*]Haven't tinkered with Wireless Advanced settings
[*]Different SSID (all lower case)
[*]WDS bridging
[*]Different WPA pass

Things I've tried on the repeater:


Connect using wizard
[*]Connect manually
[*]Connect using WPS
[*]Set the repeater IP address to the same as the Router subnet

Appreciate it if anyone has anymore ideas ☺️
