Hey guys, recently i bought a new pc(Desktop) but i had to buy a wireless adapter to connect to the internet cause there is no ethernet connection i my room.

The problem is, the connection is very unstable.
First of all, my router is : ARRIS : Touchstone Telephony Gateway WTM652
My wireless adapter is TP-Link-WN7200ND
OS: Windows 8.1 <--- (Probably the problem maker).
All drivers up to date!


Sometimes out of the blue i lose internet connection, i get Limited connection, when i troubleshoot it tells me that the wifi doesn't have valid IP configuration.

Most of the time i have really slow speed, normally on speedtests i used to get 10-12 mbps now, the latest test i scored 0.49mbps (WTF right?).

Note that i'm not alone in the network there 2 more laptops and a couple of phones.
.
I will attach as many screenshots for information as possible.

So just now while taking screenshots, i right clicked on the adapter and checked for drivers through the windows online and in installed something. Now the adapter looks like this:

First off, WiFi speeds will always fluctuate, they will match what you're paying in optimal conditions. You've already taken a few good steps, drivers and all that up to date. Next I would start looking at what might be causing some interference with your network.

Based on the IP error message you get, I would make sure you're set to obtain IP/DNS automatically (assuming that you don't have a static IP), to do this, go into start menu -> control panel -> network and internet -> network and sharing center -> change adapter settings (left side) -> go into the Wireless Area Connection properties -> click "Internet Protocol Version 4" once, then click "properties" -> make sure both IP and DNS set to obtain automatically.

As far as interference go, just remember that lots will cause this, speakers, smart TV's, radio waves, anything causing any sort of wireless signal can interfere. As well, neighbours networks can also play a big roll depending on what wireless channel they are on. Best bet for this is to google how to resolve wireless interference, as there are lots of things you can do.

If your issues persist after this, maybe look into getting a power-line device.

One other thing, since you have a network adapter, and it's USB, you will be using TP-Links software to manage it, so you may have to edit the settings in that software, unless you can enable it so Windows controls the adapter.

About the speed: I brought my old laptop here to my room, did a speed test, scored 10.62 download and 1.35 up.

about dns: there is a screenshot of those settings, it's all set to dynamic.

If it was wireless interference the problem, then i would have slow speed with my laptop too. (Remember, i brought the laptop to my room!!)

The tp-link settings are screenshoted, above.

Missed that screenshot, sorry about that. Are you running those speedtests in safe mode w/ networking? I'm just curious what kind of results you would get on both computers in safe mode. There's quite a few background programs that will pull a connection and safe mode would help stabilize that speed quite a bit to see what's causing the one device to have a slower speed. The problem with WiFi speeds is so much can effect it.

I don't think it has to do with a program draining bandwith from the new pc, cause it's new it doesn't have many programs installed. There should be bigger possibility that the old laptop would be slower cause it's full of rubbish programs.

The issue is somewhere deeper but i can't think of nothing! I tried everything i could but didn't do much :/
