2 different wifi networks in same room

[videogamingtown]

I use mobile broadband wifi modem for my internet connection this has no ethernet ports on it or anything else just a usb connection for charging or connecting directly to a pc. I have both my main pc and playstation using this wifi connection and all is working ok but i'm unable to have any files shared over the network due to it being wifi only.
I have a spare router from a setup i had last year that i want to hook up to my second pc as a music server and stream it to my phone over wifi via itunes. would this setup bring a lot of interference due to 2 wifi signals clashing or would it all be ok as long as i switch wifi channels on the devices?

Download WIFI Analyzer to your phone (mine is on android and i have no clue if there is a IOS version)

Since i'm guessing you can't change settings on your broadband wifi modem you need to see the channel it operates on.

For example if your broadband is on channel 3 then set your other router to channel 11. Also make sure both routers are on 20/40Mhz not 40Mhz only. This will keep interference to a low. Also place them as far apart as you can.

Best way to avoid interference is to set one router to b/g/n mode or just n mode and the other to AC mode if it supports it.


Main thing is to set the routers on different channels if they only support b/g/n mode or 2.4Ghz (AC runs at 5Ghz)

Each of the wireless devices will automatically try to pick the least crowded channel. If you just plug-and-play, chances are your interference will be quite low. You'll probably be getting more interference from environment, like Bluetooth, microwave oven, cordless phone, fluorescent lights, etc.

If you want to do manual tweaking to optimize it, just remember 1/6/11 are ideal channels for 2.4GHz. They are non-overlapping, which means no interference at all. use wifi analyzer or inSSIDer to see what channels the devices are using (or just log into the devices admin interface and see if they each have manual channel controls possible).

emdea22's advice about 5GHz is great. much less range, but almost no interference (from wifi or environment)
