I've tried both 5GHz and 2.4GHz, issue remains. UPD 2: after reinstalling the drivers a couple of times my download speed is back to normal when connected to my phone's hotspot, but the PC - router wifi link remains weak. UPD: I installed Microsoft's 'Network Speed Test' tool which returns results close to 100mbps (while still gives 0.5mbps on different browsers). Hopefully there's someone who understands more about networks than I do, any suggestions on how to solve this issue are appreciated. I have also tried different browsers - no difference. Basically, youtube and Google services are flying, while things like salesforce or certain microsoft services are very slow. I tried disabling the Firewall - no effect. But when I'm trying to open some webpages it takes forever. Weirdly enough, when on wifi I tried streaming 2 4K videos simultaneously and it worked, the network usage in task manager peaked at 65mbps (while on it's 0.5mbps). Other devices connected to the same wifi work just fine, while the PC is extremely slow on any network, so it's not a router problem. Wifi: download - 0.5mbps, upload - 10mbps I installed a new network adapter ASUS PCE-AC56 ('latest driver' from 1 v.7.35.317.0) on my PC which is running Windows 10 and I'm getting extremely slow download speed when on wifi: if you want to play an online-game like that, you have lags most of the time.Hi all, it's been a struggle to find a solution, so here's my desperate post. It can be that two testst are okay and the third pushes the speed up and down during the test. most of the tests are not okay (about 75%) with unstable dl-speed between 5-15mbit/s. Some of the tests are okay (about 25%) with stable dl-speed between 19-20mbit/s. i made a lot of speedtests with the 20mbit internet-line. Ping and signal-strength are good so far, but the issues are likely the same with the different versions of wlan-driver. Next i tried all the Broadcom-drivers for Windows 10 ( first i tried the drivers from Support-Website of TP-Link and Asus. Ordered two devices (TP-Link Archer T9E, Chipset BCM4360) and (ASUS PCE-AC56, Chipset BCM4352). This is going crazy on Windows 10 Pro 圆4.
