okji, can you tell me your settings in Windows for the WiFi drivers?
I would do the following just to troubleshoot:
In power options in task bar open it and change WiFi power saving to minimum.
In adapter options in network settings, do the following:
Set roaming aggressiveness to Lowest
Lastly the performance difference between my Dell and your Thinkpad could also come down to antenna placement and build differences in our respective laptops which unfortunately we have no control over.
Even in Linux you can try to disable power saving and reduce roaming aggressiveness for the WiFi adapter, just to see if that is the cause. Also consider trying hnyman's latest 22.214.171.124 Snapshot build for the R7800.
iwconfig is deprecated. (ah, it just wasn't installed). It appears my power management is already off.

Anybody got a link to an easy to understand wiki on how to compile my own LEDE build? would doing this give me noticeably better performance or just marginal? I have no idea how to begin with compiling my own.
I don't think you'll get any better performance making your own build vs pre built images unless you are adding any patches.
Use hnyman's build environment or download his firmware as I think he has some extra patches. He gives clear instructions and has build scripts. I posted the link previously. Make sure to use the "make menu config" option to add or remove any packages like Samba, OpenVPN, DLNA via build menu, before you use the "make" option to compile.
He releases snapshot builds every few days for both 126.96.36.199 and master branch so yes, they are up to date. Use the 17.01.1 builds for stability or go for his master branch builds if you want bleeding edge. He tests his builds before releasing them too.
