I've Googled my issue to my wit's end, but haven't positively determined what the problem is or found an overwhelming number of people who report the same problem as I'm having. I recently received a brand new Surface Pro 6 at work - the new i7 processor, 8gb RAM, 256gb SSD, Window 10 Pro. Other than taking it out of the box, the only thing that the IT department at my company did was add an active directory/domain so that I can login using my work credentials, as well as access our servers via VPN. While customizing my new digs to my liking, I noticed that it was taking an inordinate amount of time to install new application and get my Google Backup and Sync up and running. I started to suspect that it was a bandwidth issue, so I ran a few different speed tests (on a few different wi-fi networks) and sure enough - about half the time my download speed reports < 1.0 Mbps. I will also note that I tried these exact same speed tests with my existing Dell laptop (Latitude E7440 running Windows 7 Pro) and download speeds averaged ~ 140 Mbps. Strangely enough, the Surface Pro 6 did fine on the upload portion of the test - 30-40 Mbps, which is consistent with what I see on other devices. I've tried at least five different wi-fi networks and across the board, the MSP6 download speeds are at least a factor of 10x slower than all of my other devices. To provide further detail, here are the things I have tried (that have not helped at all): - installing the most recently .msi driver pack issued by Microsoft for my device, which included drivers for the Marvell AVASTAR Wireless-AC Network Controller (revision 15.68.9125.57 released by Marvell Semiconductor) - rolling back driver to the previous version for the Marvell network adapter - Reverting back to the stock driver that was installed on the computer from the factory - uninstalling the device without deleting the device drivers, restarting, and re-installing the device - uninstalling the device with deleting the device drivers, restarting, and re-installing the device - trying the ubiquitously reported Surface Pro 4 download speed fix (editing a registry file from a 1 --> 0 to disable a specific administrative template function) - disabling IPV6 - disabling connected standby with & without then modifying the network card power management settings to high performance and allowing the computer to put the card to sleep I'm no computer guru, but I'd put myself square in the intermediate category of experience and general computer knowledge. I have tried literally everything I can think of, but mostly to no avail. I did attempt to investigate whether my download issues were related to a specific Wi-Fi 802.11 protocol, or a specific frequency band, which has ostensibly been the most fruitful in troubleshooting. The download speeds appear to be worse using an 802.11n signal than using 802.11g or 802.11ac. At my home, I have a 300 Mbps cable connection through Spectrum with a Linksys EA7300 router. I have tested at least 7 different devices - my personal Dell XPS 9370, my old Dell XPS L702X, the E7440, my Samsung S8, my Samsung Galaxy S2, my MSP6, and my wife's iPhone 8. The MSP is by far the slowest - magnitudes below every other device. Any recommendations would be more than welcomed. At this point, I'm so exasperated that I'm considering having it sent back and getting a different device. For what it's worth, another worker in our office got the exact same device and his unit has the same download speed problem. Why would it be so much slower on DL than UL? I figure that has to be the most defining symptom of my underlying problem.
