Realtek RTL8190 Woes.

post #1 of 9
Thread Starter 
I've got an Asus Crosshair IV Formula with a Realtek RTL8190 802.11n Wireless LAN NIC on it. The problem is with both stock and updated drivers it doesn't seem to be reaching the speeds that my router is capable of putting out.

(I looked into Asus' GameFirst feature on the board, but I don't think that has anything to do with it)

I've tested the connection on several home laptops which are all capable of hitting my 30mbp/s connection speed no problem on the same network, however this NIC is only getting 5-10mbp/s and I have no idea why.

This was done after a fresh install of Windows 7 64. Any ideas?

I decided to reseat, reinstall drivers as well as Windows 7 to no avail. In fact, it ended up a lot worse than it was at the start so I ended up trashing the thing. In replacement I went out and bought a Cisco AM10 Wireless Adapter since my Router is of the same brand. I was met with no more interruptions but the same download speed as I was getting before which was constantly fluctuating in between 10-20mbps (according to speedtest and videotron) Frustrated I ended up reinstalling the OS again thinking it might be conflicting software, registry entries or other drivers. Same problem.

I've tested the connection on 3 different laptops. Two running Windows 7 and the other Mac OS X, all in the same room as my new USB adapter.

I've run out of things to try and am looking for anything to try and solve the issue.

Send it back as defective and have ASUS replace it. Be sure they pay shipping.

Would it really be the motherboard though even though it's a USB adapter and I've tried different ports?

I found that any wireless (USB, PCIe, PCI) won't achieve nearly the same connection speed as a good ol' ethernet connection.

Which drivers have you tried? Try this one.

Agreed! But it's nearly impossible to get an Ethernet cable running up to this floor. I tried those drivers last night while I still had the Realtek Card which didn't do much unfortunately. I've since switched to the USB mentioned above which gives me a significantly better connection and no interruptions, however it seems capped at around 16-18mbps.. whereas all 3 house laptops can connect at my 30mbps connection in the same area.

I meant send back the adapter, not the whole motherboard! redface.gif

Seems like it's either a) not up to snuff or b) defective ; or so it seems to me! thinking.gif

did you disable your firewall and tested it?
To rule out something like software interfering boot into safe mode with networking and see what speed it still reports. If its the same you can rule out any third party or windows software holding it back
