Hello, I bought new WiFi adapter- TP- Link AC 1750 Wireless Dual Band Gigabit Router
Archer C7. Internet speed is going really slow on my HP laptop but fast on other devices like phones other laptops and TV. I check it here: http://www.speedtest.net/

I tried literally everything.. My router location is not near any other device. I reset DNS, I use latest drivers I changed my Broadcom driver to his previous version but there was no effect so I updated it. I reset my router and laptop to their factory. I use 11th channel, 40 mHz width (I tried on 20 and auto also), my mode is 802.11 b/g/n mixed (tried g/n and n only). My Broadcom properties: bandwidth capability is 11b/g:20/40MHz (tried on 20 only also), IBSS Mode is 802.11b/g/n Auto, XPress (TM) Technology is enabled. Power Management: Allow the computer to turn off this device to save mode is not set. I called TP- Link support and they connected to my laptop through Team Viewer and checked my setting and my WiFi was slowing down again. When I disconnect it from the laptop and connect to it again the wifi is perfect for couple seconds and then it's slow. It is 0,5-2 Mbps. I didn't have that problem on my old adapter. I use 2.4 Ghz on this laptop. I checked the speed from my other devices on 2.4 Ghz also

Thank you
What USB generation is the new adaptor? What USB generation is your Laptop port?
We can try to tweek it tho!
Ok try this:

Go to www.speedguide.net

On the left hand side, you will see a link for a TCP OPTIMIZER. Click on it, Down load the client in the top middle of the next page, and run it as ADMIN.

After you run it, you will see a slider, set the slider to the speed that you got from your speedtest. Click on Apply changes. Reboot.

Let us know if this worked, and we will explain why it makes a difference in very simple terms!

I did what you told me to do and nothing changed. http://www.speedtest.net/result/7065552585

USB on Laptop is 3.0
USB on adapter is 2.0

When I use hardline connection I get the speed I'm paying for.
I use IGMP Version: V2 (tried on V3 and same problem)

Thank you
I found something out. When my wireless speed is good and I play 4k or 8k video on youtube my Laptop's fans are going loud, the video is playing for couple second well and then stops, my speed drops to 1-2 Mbps and the fans are not loud anymore . When I reconnect to the WiFi my speed is good again. When I have video conversation on Facebook I have the same problem.
