Reduced bandwidth connecting through router
I would like to seek some expert advises/solution(s) in regards to my network bandwidth issue.
I reside in Canada and currently using cable services through TekSavvy (uses Rogers as backbone). When I connect my PC (through ethernet) directly to modem I'm receiving downlink over 20mbps, however once I connect through my TP Link router (TL-WR841N) the downlink drops to 7mbps.
I've attempted to upgrade to the latest firmware and look into possible configurations on the router to see if there was any bandwidth limitation however I have yet to identify any issues.
Since I'm not familiar with network settings myself, I've decided to post my issue here for a solution. If there are any additional technical details required to assist please let me know and i'll download the software / provide any necessary traces accordingly
