For the past 10 days or so I have been having both speed and latency issues with Comcast.
History
-I have a Motorolla SB6141 consumer modem and Netgear WNR834b v2 router (Has been replaced since)
-Mid February I upgraded from 20 Mbps Comcast to 50 Mbps.
-first 2 weeks it was near perfect and everything worked within reason except wifi was sub 25 Mbps which I attributed to my old router. Wired speeds were 45-57 Mbps.
-2 weeks after upgrading to 50 my internet went to hell no matter how I connected, but every time I either power cycle modem it gets better for between a few minutes to an hour.
-This was noticed when chatting with Comcast reps where they would have me remove the router from the loop, unplug the modem, connect the PC directly to modem, and power up again. Boom, great download speeds, although up remained below 6 Mbps. It had been 11 the first two weeks no matter how I connected.
-Comcast said because my UP was slow connected directly to modem they would send a tech
-So comcast blamed my router. I bit and bought a Netgear 4500.
-Same exact issues with newer netgear so I returned it.
-I returned the WNR834b to service and deployed dd-wrt to it. After an hour I could not get over 5 Mbps download speed and up was 6. Wired was same.
-I downloaded a new game (While being connected direct to modem) and it started out at 45 Mbps and degraded to less .05 by the end. What should have been a 40 min download took 5 hours. It was the same file I d/l in December when I was on the 20 Meg line in under 45 min.
-Comcast tech arrived Yesterday (Sunday) and replaced the incoming cable and one bad end. Checked all my fittings, etc. The testing unit they bring is only docsis 2.0 so he couldn't test blast! 50 speeds. But of course he could achieve over 20 and my laptop was over 50 when connected directly to modem as usual. They can't sit around for an hour waiting for it to degrade so he left thinking it was my router.
- I went with the assumption that my WNR834 was truly bad and bought another router, Linksys E3500.
-I installed the Linksys EA3500-NP and due to power cycling my speeds resumed fast speeds for a time again, but wireless speeds never achieved anything past 15Mbps. They had been at 35 Mbps the first 2 weeks.
This morning before work I ran a test on wifi and had 13.5 Mbps.
The only thing I can think to do is go back to 20 where I was stable for 10 months.
Xbox One is unplayable. Latency test shows 185 ms which makes shooters so laggy you are dead before you see anyone. Everyone on titanfall has 5 bars of connectivity and we have 2. Nearby neighbor (3 blocks away) has the same issue. He played the beta of Titanfall without a hitch. All our problems started at the same time, about 10 days ago.
BTW,moving the xBox one to connect directly to the modem does not improve latency. No matter how I connect the XB1 to my internet (direct to modem, wired to router, wifi) I get between 130 and 250 ms latency when running the network details test provided by xBox.
I've given the xBox highest QoS priority and opened all the proper ports for xBox on the router.
I never had this issue with AT&T, but one can only do so much with a 3 Mbps DSL. At least online gaming wasn't an issue though. Is this an iPv6 issue? I see when I connect to modem my devices get an iPv6 address as does my new router.
I read reports that comcast is rolling out iPv6 so maybe they just don't have it tuned or something in Saint Joseph, Michigan. I dunno.
Any suggestions? I'm at work so I can't send any data from modem until this evening but all the numbers from my modem looked well within any suggested limits to the point of being on the best specs side of things.
