Hi,

 

This is my first post, heard about this forum on LinusTechTips youtube channel, and thought you might be able to help me with this problem.

I built a gaming PC a couple of weeks ago using the Asus P8Z77-I Deluxe motherboard, it has on-board wifi.

I also have two laptops and two tablets in my house, on these devices through speedtest.net I can consistently get a download speed of 40+mb/s on the laptops and between 20 & 30mb/s on the tablets. However on the PC I've built with the Asus motherboard, I'm consistently getting around 2.5mb/s regardless of any, or lack of any, activity from other devices on the network.

I also get these speeds at 2 other houses I've taken the PC to.

 

Things I've done so far:

-Update the drivers for the Wireless LAN from the Asus website

-Move the wireless antennas around that are plugged in to the motherboard

-For unrelated reasons I reinstalled windows

None of these made any difference.

 

I'm unable to plug the PC in via ethernet due to the modem being in someone else's bedroom, even if it helped it wouldn't be a permanent solution. Asus have said to send it back to the supplier for RMA, but I can't be bothered, this is my first self build and I'm satisfied with everything but the wifi speed, I don't want to inadvertently mess anything up by taking it apart and putting it back together.

 

Anyway... any help you could offer would be much appreciated.

 

Thanks

 

Daryl

do you have wireless devices plugged in next to your pc as interference from such things slow a network down, things like wireless house phones or a wireless headset basically anything wireless can cause this also have you tried moving the pc closer to you router as it could be the distance in between is to large

Thanks for your response.

 

The only wireless devices are phones, tablets and laptops. Whether they are connected or not it makes no difference.

The distance between the PC and the router is about 2 metres with a wall in between, basically the router's in the bedroom next to mine.

What router is it? Has anything changed with the room that the router is in? Any new tech in that room, your room or the house?

 

Also, is wired a possibility?

@Levent - I'll give that a go when I get a chance, thanks

 

@Ethnod - Thanks. Nothing has changed since I built the PC. Router is a Virgin Media Super Hub (not my choice). If the problem was with the router though, I would have thought it would affect all devices I connect. Wired is not a possibility, router is in someone else's bedroom.

Firstly, most lan cables will fit under most doors and if you can convince your housemate to let you connect wired you will have the best connection in the house, hands down. So might be a win win there

As for the router, not necessarily. I have had issues where when a friend comes over with his laptop he gets my normal IP address and I dont get another one but keep trying for the one he is using and get told to piss off :D But I no longer use cheap crap routers so thats no longer an issue. Software is finicky at times and I am assure you Virgin put no where near the amount of effort into their router software as Cisco or Netgear (in fact its almost certain its just a re-brand of some cheap crap)

 

As for your issue, something must have changed. I know you cant tell what it is but something has to have changed for the signal to be good one day and crap the next. But seeing as you have no idea what it is, and that can be very hard some times especially with wireless, lets try and find out more info.

Do you have anyone you know that has a 3rd party nic? External or internal? That might help narrow down where the problem is occurring.

Also, at what frequency is everyone else in the house operating at? sounds odd but if you are operating at X and everyone else is at Y then changing some of your settings or router settings might help

The signal was never good with this machine. As I said in my OP, I've had it two weeks. In those two weeks it has always been slow, and it has performed slowly in my house and 2 others. It's the machine not the router, trust me.

Well then I would recommend trying an external NIC, see if you can get a loan of one from a friend first. You can get half decent ones for not too expensive so that my recommendation. Or try wired. 

You can also gain an idea of what might work for you by trying someone laptop at your desk and seeing what kind of connection they get and then getting a NIC along the same specs as the one that works

I have two laptops and two tablets. The tablets get over 20mb/s. The laptops get over 40mb/s. They are within 1m of where the desktop is, the desktop gets just over 2mb/s, and is closer to the router. I can get over 40mb/s on the laptops from anywhere in the house though, distance is not the issue.

I would like to have the desktop up to the same speeds on it's own, without an NIC card, as the motherboard doesn't have any available slots, it's a mini itx board with one PCI express slot that is taken up with my graphics card. And I don't want to spend money on making the machine capable of something it should already be able to do. As I said it's only two weeks old.

Thank you very much!!! Now that I'm home I gave your advice a go. I didn't have exactly the same options as you, but I made some changes, did another speedtest.net and got 34mb/s which is still slightly slower than my laptop, but nearly 16x faster than it was!!

Thanks again
