Windows 10

Hi,

Im hoping someone can help?

I have a Deco M4 installed as router mode, about 3 or 4 weeks ago i noticed both my Linx7 tablet and Lenovo 100s Laptop were not connected to the network which i thought was strange but tried to reconnect and i got "Unable to connect" so i restarted both devices but still the same message so i hit "forget this network" and then restarted, re-added it but still the same. So i rebooted the Deco and then the laptop connected but had the warning "This network is using an old protocol and may not protect you" which i thought was strange but the tablet still would not connect, so i restarted everything laptop, tablet, deco and once up everything connected and then about 5 minutes later the connection was dropped again. So i factory reset deco and checked i installed the latest WiFi drivers for both devices, they both connected and then 5 minutes later dropped connection.

The only common link between the laptop and the tablet is the WiFi card they are both 

Realtek RTL8723BS Wireless LAN 802.11n SDIO Network Adapter

After running out of ideas i connected TP-Link Support who have been very helpful but still had not luck, they had me do the following

• Change DNS to 8.8.4.4 & 8.8.8.8
• Disable Fast roaming & Beam forwards
• Check the gateway address for both device's (make sure they were correct)
• Ping the Deco
• Wireshark packet capture (no useful information was found)

on top of the above i have ran the following in Window CMD

netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns

but still no luck, can someone help please?
