Windows 7: TP-Link TL-WN722N Problems

TP-Link TL-WN722N Problems

Hey all,

I made my first build yesterday, and so far things have gone relatively smooth. The biggest problem I'm having at the moment is with my internet.

Network specs before I go any further
OS: Windows 7 Ultimate 64-bit
Network Card: TP-Link's TL-WN722N 150Mbps High Gain Wireless USB Adapter (Bear in mind, I'm only getting like 6Mbps download speed at peak times; fast compared to my laptop's regulra 3Mbps speed)
Router: Linksys WRT110 (A floor below me, and a room over, so the signal strength isn't the best it could be. Using a direct-wired-connection is out of the question)

Basically, my internet will go from lightning-fast, and drop immediately dead the next second. It is constantly resetting itself and re-connecting itself to my router, every couple of minutes.

I've power-cycled my router and modem more times today than I have in my entire lifetime; to no avail.

After I got my computer up and running, I used the drivers from the installation CD that came with it, and got the internet running. However, things were slow, so I decided to update the newest driver after all the other drivers were finished and installed. Honestly, it only made it worse.

I've even reverted back to the original driver, and now I can't even connect period.

I updated my EFI Bios via EZ Flash, thinking that it would help, and it went perfectly, and but it only made my connection problems worse. (At least I was able to connect before)

My laptop sitting a foot away from my computer has no problems whatsoever, and running a "tracert" on both computers one-after-the-other, the ISP servers were not lagging on my laptop whatsoever, but they were relatively higher on a few servers for my custom-built computer.
The servers for the website I was testing out (I used the WoW site) were like 3000+ms, whereas the same servers for the same site on my laptop were much less than that.

My internet has been spiking a lot the last week, even before I built the computer, however I feel like this isn't the problem; since I can use my laptop just fine while my computer is lagging away.

I'd say the ratio is 90% slowness to no connection at all, to 10% regular speeds. (That was before the BIOS update, and now I either can't connect period; or I'll have normal internet for a few seconds, it loads up my Google homepage right away, and then refuses to load anything else; then the cycle continues)

I haven't even been able to fully patch WoW in the course of an entire day's time; and downloading drivers takes excruciatingly long. (Unless I try it at a time where it's working, which then my speeds are completely fine)

I'm considering buying a high-gain wifi Signal Booster, like the Hawking HSB2 on Amazon and Newegg, but I fear it will not resolve my problem.

If it is worth any information: During all installations I have only been able to install the drivers, since for whatever reason the installation CD told me that the utility which comes along with the TL-WN722N driver, was not compatible with Windows 7 64-bit. (Despite the fact that all the reviews, and the box itself, says that it works with Windows 7. You'd think they'd make a note if it didn't with 64bit)

Does anybody have any idea what the problem is, or how to fix it?

Thank you so much!

Trying to find information on the TL-WN722N device.
The website appears to not exist though, so I'm rather confused.

It should be Tp-link.com ; but now that you mention it, I wasn't (and still can't) connect even now on my iPhone. Yet, last night during first install, I had zero problems connecting. Even early this morning I could.

Try looking for it on Newegg, it's just a white usb looking thing with an antenna.

Curious perhaps you could help him out some?
I get a redirect to this

Which produces a page my browsers will not display.

Unfortunately, the latest utility is what started all the more serious problems, along with the latest driver. It was still relatively slow before I installed them, but when I installed the utility, I got an install box that had a lot of messed up text characters in the title during the install (the drivers don't have this problem), and then I got an error that said the utility isn't compatible with Windows 7 64bit, and to only install the driver, which I did.

At this point, the internet couldn't even find my router, and I had to go in to the program files to remove the utility, then uninstalled the driver; restarted, reinstalled off the disc, and the problem persisted.

From there, I thought updating my Asus EFI BIOS might help, but since then it's been worse: I can't even get a connection to stay passed the homepage on my browser before it disconnects on me; which leaves me here clueless.

Might want to look into whatever is blocking it on your end, seeing as it even says "block" in that link you posted.

You can see the adapter here,

Newegg.com - TP-LINK TL-WN727N Wireless N Adapter IEEE 802.11b/g/n USB 2.0 Up to 150Mbps Wireless Data Rates Support 64/128 bit WEP, WPA/WPA2/WPA-PSK/WPA2-PSK, Wireless MAC Filtering

and if it helps any, the user guide,

Oh looks exactly like my belkin usb wireless.
I had issues with it, the solution was.

To Disable Selective Suspend:

open the control panel
go to power options (you may have to set view to small icons)
click change plan settings
in the window that opens:
click change plan settings
click change advanced power settings, expand usb and ensure usb selective suspend is disabled.

It's actually a little different than that. It's the 722 model; not the 727. =]

Here's a link:
Newegg.com - TP-LINK TL-WN722N Wireless Adapter High Gain IEEE 802.11b/g/n USB 2.0 Up to 150Mbps Wireless Data Rates 64/128 bits WEP
WPA/WPA2, WPA-PSK/WPA2-PSK (TKIP/AES)


I'll try disabling selective suspend when I get back to the compy in about 20 minutes.
