Wifi disconnects when another device connects to the router

[kennahmf]

Hi guys been experiencing an issue where my acer laptop disconnects from the router, a AZTECH wireless extender, when another device connects to the same extender.

otherwise the main modem is CISCO.

my laptop runs on windows 7 professional x64

i also attached a screenshot of the xirrus program

disconnection mainly happens when im playing online games which sucks so i hope someone knows whats up and can help!

Does router DHCP has enough IPs to assign?

Try another channel in wireless options in router interface.
