Internet speed varies greatly by room

[ShadySocks]

I have an asus X550za, it only supports 2.4ghz.

I have an ASUS 1750AC router.

I have 100/10Mb/s internet

 

When I move outside the room with the router, I get 0.2 mb/s, but when I am in the same room I get 30 mb/s, both rooms have 5 bars signal strength. How could I fix this?

If the signal is still strong then it may be 2.4ghz interference from something nearby.

It's wifi, what did you expect

Connect some of newer devices on 5ghz channel for larger bandwidth but the range is lower than 2.4ghz. 

 

Also what speed test are you using?

 

You should use iperf for actual wifi performance results.

I could tell you at least 5 things that could be causing your problem.
-thick walls

-other AP interference

-too many devices at once

-low power output

-bad AP placement

 

You need to troubleshoot each and every one. First make sure your AP(wireless router) is high enough, like on a table or even higher(and away from walls).Set all the antennas completely vertical.

Log into your device  configuration portal and make sure the output power is at 100%.Try different modes such as b/g only or b/g/n, see if that makes a difference.

Review how many devices are active and make sure you own all of them(someone else could be using your wifi).

Finally download Acrylic and scan all the networks, check the channels they are using and set your SSID channel to a different one.

If everything fails then you might need a wifi extender.

I restarted computer and now I get 50mb/s where I once got 0.2
