Hello. I'm using this TP-Link router as a range extender for another Mikrotik Router (with RouterOS v6.40.2) at my home. The TP-Link router works great when configured as AP, but in RE mode, whenever a device connects to the router wirelessly, at first the connection establishes without any delay and internet can be accessed. However, just after a few seconds, the connection indicator shows "connecting" status again and internet becomes unusable (like the following snapshot). After about a minute or two, the connection becomes stable again.






This happens every time, no matter what devices try to connect. I've checked with macbook pros, iphones and androids. This is extremely annoying. Whenever I wake up my mac from stand-by, it takes this 1-2 minutes to connect to the router properly.


Can anybody please help me out?


Thanks.

How far is it from the main router? The RE needs to get 3 bars signal at least from the router.

Sorry for the late reply. I did some more research and here's the result.

The range extender is just in the next room of the main router and it gets full signal strength from the main router. I'm trying to connect to the range extender from a point where the main router signal is too weak to provide stable connection. See the image below where you'll be able to find signal strength, channel info etc. of both the routers.





I've reproduced the incident about an hour ago and right after that logged into the range extender and went to the System Logs section. There wasn't any ERROR level log at all. So I took the dump of the whole log and you can find it below.

As you can see, during the disconnection-reconnection incident, the range extender didn't log anything at all. That's why I recorded the wifi log from my macbook pro during that incident and you can find the log here: https://pastebin.com/jURm4u1V

I've also attached below various screenshots from the settings of my range extender as well as the main router for further reference.





























Main router settings: https://imgur.com/a/FUJWl

Also note that I cannot connect none of my android devices to the range extender BSSID, but all the android devices can connect to the main router BSSID. Apple devices can connect to both, though.

Any thoughts? Thanks in advance.

I faced the exact issue. After lot of stugle I finally found a solution.

 

I can't say it is really solution but I can say it a patch for our problem. 

 

 

Login to tp-link router and change DHCP option to enable from auto.

 

This one fixed my issue. Hope it will help you as well
