Slow wired connection
Have an issue with a slow wired connection - looking for some ideas as to how to identify issue and rectify.
Archer VR2100 router
ISP is Hey Broadband and have 1gb FTTP - have their modem ( Adtran SDX611) in bridge mode so I can use my own router
Own router is in the - wireless router mode
QOS is disabled
laptop connected via Ethernet cable directly to ISP modem gives expected upload / download speeds - 900mb ( used both cat5 and cat6 cables )
when connecting laptop to LAN port on router, speeds drops by more than half to circa 300mb - same issue using cat5 or cat6 cables (cable types not mixed)
firmware is current
wireless speeds are less than the decreased wired connection though laptop connection speed to router shows upwards of 700mb - but suspect when I fix the wired issue then wireless will improve
Any suggestions appreciated.
