My wireless network disconnects when my xbox 360e is on

hi guys

When i turn my xbox 360e on (which is a wired connection to my router) my wireless network disconnects and all my wireless devices around my house cannot connect to the internet or it slows it down about 90%

like i will get on a wireless device like my laptop and try to load a page to no avail but as soon as i turn off my xbox the connection is back to normal

would appreciate some help

i have a bipac 7800nL

and my xbox is hooked up to my all in one hp envy recline 23" pc

thanks

:)

 

Why do i keep disconnecting from xbox live?

My network equipments are:

A Westell (not sure if spelled right) DSL Modem and a Netgear Wireless N 300 router.

Other devices connected to my router are:

2 Desktops(wired), 2 laptops (wireless), 1 netbook(wireless), Playstation 3 (Wireless), Wii (wireless), 2 Ipod Touch's (wireless), and my xbox 360 (wires).

I know it may seem like a lot of devices on one home network, But usually there is very few of them connected to the internet at one time and i prioritized connection for my 360 on the router.

Only my 360 disconnects and causes network/internet disruption.

 

Xbox one X disconnects from network every time i turn the console off

I've been having a problem that every time i turn my xbox one x off it disconnects from my wireless network and when i turn it back on my xbox can't find any network to connect too. The problem is fixed if i disconnect the power cable from the console and
have it power completely off, but then i am still forced to search for my wireless network and reconnect manually to it
