Use system restore to a time before installing fences.If it was successful i'd run hard drive diagnostics,file scan first then a sector scan & a virus scan afterwards,unless win 10 was an upgrade then your on your own.
other options before doing system restore:
do a hard drive file scan first,it's a 3 step process & is quite quick.right click on drive C,select properties,tools tab,error checking & check now button,should be a tick in the first box after hitting check now so start it
reboot after scan finished not before checking log
failing that
start support ticket
device manager may have info on network device or check event viewer
can't help much else as it really doesn't make sense as to why fences would have an effect,i suspect there's other issues at play.My rule of thumb is "you can't install yet more software on an already buggy computer".Well that's where i'd start & slowly work backwards to try to determine where the issue lies.As for my upgrade comment most suggest fresh install as you just don't know what balls up windows install did..lol..
lastly did you
