Bandwidth Loss Through Router, New Tested Equipment, Has To Be Some Setting?
OK, I am at my wits end with Cox and Linksys and am really hoping someone here can help. I am going to go into allot of detail, because of how much frustration I have had with several "technical" support reps.
I have Cox Preferred Internet with 50 down 5 up speeds, I get 50+ at my modem, both my old Cox ePhone version and my new Linksys CM 3024 DOCSIS 3.0 24x8 cable modem (got rid of phone service and purchased my own).
Once I go through a router, the speed drops to ranges from 12-41 down, averaging around 35 down. This is wired or wireless and has happened on all routers I have tried.
I just purchased the Linksys Max-Stream AC1900 MU-MIMO Gigabit router to ensure bandwidth capacity. I have had an ASUS and a Belkin in the past, and again, never got full speed through them, always seems to cap around 35mb down.
I have been through the ringer with Linksys, examining every setting in my router that their "technical" support has to offer, which from multiple calls is just a scripted manual that inevitably leads to a misleading "device must be defective" outcome and request for an RMA. Unfortunately, I have tried this with 2 different models of the exact same unit and I can't believe I got unlucky enough to grab 2 defective units off the shelf. Especially since it was the same results with previous routers.
So I continue by going through Cox, and they check signal strength, reset modem, blah-blah-blah, typical phone support script, send out a technician, who verifies my findings but can't offer anything to resolve the issue at the router. I am stonewalled by service reps who have no technical knowledge and can't get to the issue.
I have googled and seen many similar posts, with the usual "update your firmware", "turn off IPv6", "check adapter settings", "get better cables", "disconnect/turn off all other devices", "set the router in a better place" (even though results are both wired and wireless), etc, etc. The only thing that even approaches touching on a possible resolution is when people talk about duplexing (but this shouldn't be the issue as I have gigabit ports, not just 10/100).
I feel like this has to be some sort of protocol conflict, or capping QoS setting internal to the signal or settings as it goes through my equipment.
I have tried changing from NAT to Dynamic Routing in the advanced routing settings, but I get no internet using Dynamic Routing. Perhaps some auxiliary settings need to be made when using Dynamic Routing???
I even checked the reporting on the Linksys router and it shows that the WAN is receiving in gigabit, but the LAN ports all show 10/100 connection (but this could/should be an auto detect defaulting to lowest bandwidth needed at the time). I brought this up to 2 different Linksys "technical" support reps, but neither even addressed whether the unit has an auto detect function, much less if the LAN designation can be manually set (never found a setting in all of my own searching).
So, to recap:
Cox Preferred Internet 50/5 service, signal good into residence.
Linksys CM3024 DOCSIS 3.0 24x8 Cable Modem, receives good signal, sends 50mbps+ download speed out the Internet port, 5mbps+ upload (never seem to have issues acheiving this).
New Cat6 cable to Router.
Linksys Max-Stream AC1900 MU-MIMO Gigabit Router, firmware up to date, ping tested, WPA2 set, receives via Cat6 in WAN utilizing Gigabit, LAN ports distribute showing 10/100 on new Cat6 cables, LAN and Wireless 2.4 GHz and 5.0 GHz only acheive average speeds of 35mbps down (have gotten a couple of results to hit 40, allot of results in 20's, some as low as 12), and usually get around 5mbps up (again, never really had an issue on the up).
I see several posts/complaints about this with several ISP's when I google for resolution, but no working suggested resolutions. Does everybody just give up and accept that they don't get what they pay for?
This wouldn't be as annoying if I could even get solid 40mbps, but I get drops in speed that shut down streaming media or make downloads take forever. I just want the speed I request and require.
