Frequent WiFi disconnects but not so random

Bambacha · 19 Apr 2021

Hello there!
Recently I've been having a problem with my WiFi connection of my wireless Win10 laptop. After I set up an extended network to give internet access to a second flat (located in another floor), I've been having a constant disconnection problem. The model I hastily drew below is a rough sketch of the network.

The problem occurs on the laptop that is connected to the isp router wirelessly. Especially on the Win10 laptop, the disconnections show up on the event viewer as "Wlan autoconfig detected limit connectivity attempting automatic recovery". The disconnections always happen on 2 occasions: when I switch on the TP-Link client and immediately power on my pc2 and one more time randomly when the traffic on the network situated after the TP-Link is heavy. None of the other devices are disconnected (both the ethernet-connected pc1 on the isp router and any device connected on the access point be it wireless or wired).

Any help on why this occurs will be appreciated! Maybe I messed something up while extending my network, maybe there is something disconnecting the laptop due to a conflict.
Specifications: Laptop connected wirelessly to the isp router and pc1 both have Win10 x64 Education 20H2 build 19042.928, pc2 has Win7 ultimate sp1 x86. The following is the settings panel of the TP-Link that is locked on the isp router and acts as a wireless bridge for the other flat's network. All devices have their adapter settings set to auto

Why is the access point on a different subnet? You need to check the signal strength on the laptop there are free tools on me store it may simply be the change of the channel on the router if something close is using the channel

After experimenting, Samuria seems to guide me to the right direction.
I did 3 things on the access point and it seems that they solved my disconnection problems:

Changed the subnet of the access point from 192.168.2.xxx to 192.168.1.xxx (the same subnet of the isp router)
Set the access point to a static IP inside the 1.xxx subnet
Disabled the DHCP server of the access point and gave all DHCP handles to the isp router

Now all devices on both flats are in the 1.xxx subnet and the wireless disconnections of the isp router stopped. Let's hope that remains true from now on.
Many thanks!
