Hi!
I've recently upgraded to a new computer, with a fresh install of windows, and I have severe packet loss on the new system for no reason that I can find or fix. I am using a WiFi connection, however this is due to living at university and not having the option to plug into Ethernet in my student accommodation. It also mean's I don't have the ability to change any of the settings for the router. I've tried running through every recommended change to help alleviate packet loss that I can find online, no to avail. This includes changing the default packet size in windows to the max packet size of my router so there are no packets lost due to size cap, which is rarely a problem anyway, but I wanted to try everything I could find. Interestingly enough, my old computer, which I have switched back to for now while I try to get this resolved, works perfectly and has zero packet loss. Latency and up/down speed aren't an issue on either machine, both perform perfectly in that regard.
The specifications of the two machines are as follows (If it's relevant):
Old:
CPU - Core i7 4770
GPU - MSI Ventus RTX 2070 8GB OC
RAM - 4x 4GB DDR3 1600MHz
MB - Gigabyte H87-D3H
NIC - Intel Dual Band Wireless-AC 7260
Windows 10 Pro 64 Bit
New:
CPU - Ryzen 5 3600X
GPU - MSI Duke RTX 2080 8GB OC
RAM - 2x 16GB DDR4 3200MHz
MB - MSI B540I Gaming Plus AC
NIC - Intel Dual Band Wireless-AC 3168
Windows 10 Pro 64 Bit
Let me know if anything else is relevant...
I am almost totally sure that the fact that it is WiFi isn't the problem, as both computers are within 5m of the router, and both are utilizing the 5GHz band which according to a WiFi analyzer I used, is clear and uncongested. The only difference in performance network wise is the packet loss. I can't gauge exactly the severity of it, however I do know that it is consistent and doesn't falter. It is bad enough to the point where any video game that requires an online connection is unplayable. Also, running the ping command via the command prompt for a long period of time shows about 20% of the packets are lost.
Massive thanks in advance for any help or advice. :)
