When both identical network cards are on performance is awful!

Ease · 24 Oct 2015 at 10:01

I have two PCs, each with an ASUS PCE-N53. The driver version installed appears higher than any available online (on ASUS' offical page or elsewhere).

When one PC is on, I get ~24mb/s. When both are on they each drop to about 10-100kb/s with frequent intermittent dropouts. What can I do to fix this?

This might sound stupid however have you had any popups or anything about conflicting IP addresses. Because they are the same make they might have the same MAC address. open cmd and type ipconfig and check the ip address' and physical address and make sure they are different.

No pop ups, and IP addresses don't conflict. This is doing my head in, and my girlfriend now complains that when my PC is using the internet her phone is getting awful connectivity (pages loading in minutes rather than seconds).

So your wireless connection is 'I get ~24mb/s',
you've got connection/interference problems or something isn't configured correctly.
What router do you have ?

I've got the TalkTalk Huawei HG635 VDSL 802.11ac router (aka "Super Router").

It reports ~28mb/s, but I see ~24mb/s on speedtest.net on my PC which is connected wirelessly using the aforementioned wireless card. When I switch on my partners computer (placed a couple feet from my PC) the internet is intermittent, and download speeds range from 1kb/s - 20kb/s, occasionally reaching as "high" as 100kb/s.

We've had them set up like this for months, but have only noticed the problem since we both upgraded to Windows 10. I upgraded to Windows 10 first, and I don't believe we had a problem until my partner also upgraded. Though this may be coincidental.

Can you change your pc to use 5ghz band and partners to 2.4ghz?

I changed my PC to 5GHz only, and my partner's to 2.4GHz, but the issue still arose.

Also, I noticed last night that my PC also stopped my Android phone from accessing the Wifi - the phone could see the network, and reported no faults, but I couldn't access any sites/online apps on it.

Very tempted to buy a new card, but don't want to waste hard earned money if it won't certainly fix the problem.

Have you tried running inSSIDer i think version 3 is fee but you have to pay for version 4. So have a look around for version 3. Have a look at the signal strength ext and see if it changes when the other devices start to use it or see if the router is on a congested channel and try to change it.

Have you tried putting the super modem thingy in modem only mode and trying a different router? Maybe one from an old ISP you used to use or something. To see if you have the same wifi issue with that (to rule out the super modem)
