Bandwidth Issue

Team,

I need some help troubleshooting a bandwidth issue.  First I my ISP is Comcast -Infinity, the cable modem = Motorola MB8600 (DOCSIS 3.1) ; Router = NETGEAR – AC750 Wireless Duel Band Gigabit Router  - R6050. I have the Blast Internet package which should be 250 MB; only because Comcast could not get the Gigabit service to work. My issue is if I connect my workstation downstairs beside the wan equipment I can consistently get 240 MBs. I have a gigabit switch downstairs and upstairs in my office. I have replaced all my network cables with CAT6 cables and have a 50 ft CAT6 connecting the two switches. If I do a speed test from upstairs either connected to the switch upstairs or directly to the MODEM I average from 70 to 82 MBs. I recall Ethernet has a maximum of 100 ft – is that still correct? I am running the cable from downstairs outside to the attic then between the drywall. You think maybe I need a certain type of CAT6? I believe I have shielded twisted pair. Another issue is when I do a speed test connected to my WIFI; I am only getting about 10 MBs. If I can get the WIFI speeds up I will forego dealing with the wired connections.

   A 100MHz physical link somewhere could explain that, and a bad cable
could explain a 100MHz physical link.  What do all the port-status LED
indicators (or software reports) indicate?  Gigabit speeds, or less?

   Did you have a problem with the old cables?  Who assembled and tested
these new cables?

   Not now, not ever.  100 _meters_.

   If you haul the distant equipment to the neighborhood of the fast
connection, and use known-good (short) cables to connect the
troublesome equipment, is the trouble still present?

   It would be unusual to get better speeds by radio than by wire, if
the wire works properly.

Re: Bandwidth Issue

Thanks for the information; I ordered the cable from pc connections. I am ordering a better cable; hopefully. The question about getting a  better radio connection; is this a limitation of the router or is 10 or 11 MB typical for the R6050?

   I'd study (or eliminate) the old cables before buying more new cables
which may not help.

   "a  better radio connection" to _what_?  A chain is only as strong as
its weakest link.  If your client device is old and crippled, then the
best router in the world may make no difference.  If the radio channel
is congested, ...
