I am having an issue with my EA3500 router. Here is what I do:
1) Plug PC to modem with a 4' CAT6 cable. Run speedtest.comcast.net and see 100MBps or more.
2) Plug EA3500 to modem with same cable, connect via wireless from EA3500 to PC. See 30MBps (3x slower)
3) Plug EA3500 to modem with same cable, connect via similar CAT6 4' from EA3500 to PC. See 30MBps (same slow as wireless)
I have tried cat5-e as well as cat-6 cables, and assorted cables from 4'->25'. I have reset the router and modem as well as PC. I have installed the latest firmware.
Any help woufd be appreciated.
