Yeah.. i was about to say the same thing...
Not usually a good sign, when the detailed specs, dont give the FULL model (or possible models) of the wireless in the unit 😞
For anyone reading through this thread, please do not go out and buy a cheap USB adapter. You will most likely end up with a single data stream, single channel USB adapter which could / will cause more grief than what it is worth. While most routers will switch back and forth between 20 Mhz and 40 Mhz wide channels, and switch between single, dual or triple data streams for the devices that you own and operate, some modems or routers will not, such as the CGN3. The CGN3 will lock down to the lowest common denominator, or in this case, single channel operation, bringing your faster devices down to a crawl. If you are convinced that a USB adapter is the way to go to solve slow wifi performance, please spend the money and buy a good one, which will solve the problem instead of creating more problems. Issues with cheap USB adapters have been seen in the forum previously, so, moral of the story, buy better quality equipment. Fwiw.......
Crtl - Alt - Delete brings up the windows task manager, which will allow you to see what programs are running. There is more to running a speed test than just physically running it. You have to know whether or not the test platform that you are using is up to the job, and that depends on the processor, amount of ram onboard and hard drive speed. As an example, using a gaming laptop, or pc, I see 330/22 Mb/s on wired tests. The gaming laptop (Windows 8.1) will essentially match the wired speeds on wireless using 802.11ac. Our Acer laptop, also running Windows 8.1 will only run 200 Mb/s on a wireless test. The Windows RT, might get 50 Mb/s? So, your speedtest results really depend on what your test platform can do. Out of curiosity, what are you using for a laptop or pc?
The Acer in question is a Acer Aspire S3-391 with 4 gigs of ram, Samsung Pro 840 SSD and 802.11a/g/n. This runs on a 5 Ghz network, and maxes out at 203 Mb/s down and 21 Mb/s up. The adapter is a Qualcom Atheros AR5BWB222 Wireless Adapter. If I remember this correctly, it will max out at 320 Mb/s down, 22 Mb/s up on a USB Gigabit ethernet adapter.
To see if anything is running on your wired / wireless adapter, bring up the Windows Task Manager, select the Performance tab, and then the Ethernet selection if its wired. I presume it will show "Wireless", if its connected that way. That graph that comes up will show if anything is running through the connection.
For a more detailed view of what running on the connection, go Start....All Programs.....Administrative Tools......Resource Monitor. When that comes up Select the right hand Network tab and expand the various data windows so that you can see all of the activity within the available categories. If you stop or kill all of the processes that you are aware of that use the internet, you should see no activity at all. If something is using bandwidth, it will show up. The problem might be that you will see usage by Windows svchost.exe. Is that legitimate or not might be the question.

yep, no surprise there. What model of Acer laptop are you running exactly ? Just guessing, but disk access time might be an issue unless you replaced the hard drive with an SSD. RAM speed and quantity might also be a contributing factor. Do you defrag the hard drive on a regular basis, and, how long has it been since the laptop was reloaded from scratch? And, keep what I said earlier in mind, our Acer won't really go beyond 200 mb/s on a download test, but our other gaming laptop (Asus) has no problems what so ever. The difference? Much faster processor, more memory which is also faster to boot, and an 802.11ac wireless adapter. The choice of equipment you choose to test with can make all the difference in the world.
