So, i recently upgraded from a 100/10 line (fast but not fast enough) to a 1.5gbps/980mbps fiber line through my ISP (Bell Canada) the new modem they brought has a 10gbps port on it. i figured perfect, my pc has a 2.5gbps intel network card in it. so ill get full speed. i was wrong.
symptoms as follows :
Plugged into 10G port on modem Via CAT7 cable:
1. inconsistent speedtest speeds, nowhere near half of my rated internet speed, choppy on both upload and download
2. same inconsistency shown while downloading anything, gaming is fine and latency to servers is extremely low
3. steam will use the full speed for about 15 seconds on a large game download. them drop right to 0, no disk activity either, then pick back up (not a write bottleneck, steam is pointed at an M.2 PCIe SSD)
Plugged into a 1G standard port on the modem via same cat 7 cable:
1. more consistent download upload speeds showing 930mbps/910mbps
2. downloading from browser is fine, so is other game launchers, gaming and latency remain fine and low
3. steam performs more consistently, but still only pulls around 250-300mbps before dropping to 0 in the same fashion as before
the problem with option 2 is it caps me below 1gbps so i dont overload the port, and steam is just annoying both ways, and option 1 would be great if it actually got to speeds its rated for, and the cable is brand new, i installed it today. its also a 50 foot cable, which even cat5e would handle theoretically for my internet speed.
any insight into this would be great, as its annoying me to no end that i cant make the 10G port behave and do its job. and that steam is this broken is beyond me.
EDIT: Issue solved, defective hardware from bell, new modem on the way.
