Slow download speed on Realtek RTL8811AU Wireless LAN 802.11ac USB 2.0 (range or something else?)

[Bark]

Ok so I'm thinking that my download speed is because I'm across the apartment from my wireless router, but I wanted to make sure that is why it is slow because the fastest download speed I get is around 700 KB/s. I think I'm about 50-60 ft from my wireless router.

If it does seem like there is something wrong with that speed, let me know what might be the problem if not the range.

If it is just the range, does anybody know any wifi adaptors that could handle that range and have fast download speeds because, right now, it take about 13 hours just to download a 26gb game. Please and thank you.

Try using/comparing both 5Ghz and 2.4Ghz range; see which frequency offers you better speed+range overall.

Try a different download server in Steam Client, or whatever you are downloading.

Try changing the Modem/Router config > changing the Wireless Channel to something else besides the default one.

Others around you are going to be on various wireless channel# and that can impact your overall performance as well.

Ok. I have changed the wireless channel already, but that didnt fix it unfortunately. How do I test out the 5ghz and 2.4 ghz range?

Wait. I think I know what you mean. A couple of days ago, I went to my network adaptor and changed it to 802.11b but it didnt really make it faster. What sucks is that my surface pro 4 can download♥♥♥♥♥♥just fine from the same distance. It can stream video at 1080p easy, but my computer take 15 minutes to load a 5 minute video in 1080p

You should have the 2.4 and 5.0 setup as two separate SSID
So you can choose from the listing which to login to; as only device that support the AC 5Ghz would be able to even get on that.

[Bark]

I'm not exactly sure what you mean.

I did find another place to hook in the cable that is about halfway between my computer and where it used to be but I can now only get up to about 2.7 Mb/s which is a lot better but is still a little slower than Id like it to be seeing as how I pay for fast internet.

[Bad 💀 Motha]

In the Modem/Router Config; under the Wireless Setup you should have settings for both the 2.4 and 5.0 Ghz; SSID is the Network Name; to which should be a separate name set for both of these. As they will act as separate logins for either range.

What speed plan do you have with your ISP (download / upload speeds)?
So we know what your max possible could be. Otherwise just saying speed #s and thats slow, doesn't really mean much.

Remember the ISP speed plan is listed in MegaBits per sec
Typically when you download a file, it will show in MegaBytes per sec (1/8th of your actual ISP speed)

I've encountered exactly same problem. (maybe)
It is that very low download speed (3Mbps), but very high speed upload speed(220Mbs).

"Update the Realtek 8812AU Wireless LAN 802.11ac USB NIC manualy
and disable two options which is LdpcCap and StbcCap"

http://iptime.com/iptime/?page_id=67&uid=18157&mod=document

after that I have 210Mbps (DN) and 30Mbps(UP) (I don't know why upload speed drops;()

I hope it may help you. :)

The NIC Driver does have a config, check that.
You have things like "Buffer" sizes. Sometimes if the buffer is set too high, it can create issues and further delays in data transfers. The defaults are not always the best. Especially a high buffer on a slower machine.

But yes, Driver version helps improve things too; a majority of users never update their Network or Audio Drivers, cause they figure if it working, then it's fine. The thing is, you do look to GPU Drivers for performance benefits right? The same can be said for any Driver in general, for any device.

Thanks ya'll. I'll try those out.

Morning everyone, I am having the same problem when running a 80 mbps, download speed on other devices my RTL8811AU can't download for ♥♥♥♥. I have tried finding drivers, but half of them are sketchy as ♥♥♥♥. I have tried almost everything on here and I am still lost.

Drivers from where? Get the Driver from the branded site of the device maker.

wifi B is slow.

change wifi to N (fastter than A/B/G) or AC (fastest), if you have it

[Bad 💀 Motha]

You basically must do Wireless G / N (2.4Ghz) or AC (5.0Ghz)
If you want any chance of the WiFi doing a decent speed at all.

Download TeamViewer and i can set this up for you.

[rotNdude]

Please post your computer specs and what OS you're running. If that USB adapter is inside a desktop computer and has no external antenna, that may explain it.

This is a really good answer, in your adapter advance tap, change the wireless mode to IEEE 802.11.ac. That would give you a fasted speed
