So I turned my old Buffalo router into a bridge, and I get download speeds of around 130Mbps (out of the max 250 ish with no router)
So whatever the issue is, the router refuses to play nice with my computer.
What setting or issue could there be for a router to not like the computer specifically? Would computer naming/mac address conflict cause this issue?

Seems like something on the one PC is possibly causing the issue.

I would do the factory reset the router, manual load of FW, reset again from the good working PC. When this is going on, be sure to do a Ipconfig /release then ipconfig /flushdns from a command line on the effected PC. Then completely disconnect the PC from the power outlet to be sure that all power drains from the PC for at least 5 minutes and disconnect the LAN cable from the PC. After the router has been re-flashed and setup from scratch and 5 minutes has passed with the PC being fully disconnected from the wall outlet, power ON the PC, reconnect the LAN cable and check the IP address on the PC to see if the address changed. It should have a new IP address and be different.

Test. If the PC still fails and all others work, something on the PC or the adapter with this one PC needs to be looked at. I would get a 2ndary NIC and installed it, try something with a broadcom chipset and test.

Turns out under services on the computer I had a microsoft QoS thing installed, deleting that helped return at least some download speed and upload speed. That said I still get better speeds using the router as a bridge. I might just have to stick with that solution for now, until I can think of other things that might affect the pc.

Thank you for the help nutz.

Sounds like your getting there. Something on the PC seems to be effecting what your seeing. Hope it works out for you.

Good Luck.

I had a laptop that refused to play nice when wired.  I found some setting to change that was pretty deep and all is well. the upload speed wired was what you had experienced....  HORRIBLE...

Thanks for the feedback RYAT. Seems like there is a NIC configuration on this one PC that was hanging it up. Seen various issues with NICs over the years. I usually leave NIC configurations at default unless something comes up that's specific. NICs and configurations don't usually need any kind of configuration.
