West to East Speed Tests Very Slow Now at all Times of the Day and Night

With 400/10 HSI as part of my Premiere Triple Play, all speed tests have recently dropped dramatically for me eastbound from Portland, OR towards the midwest and east coast servers, regardless of the Test sites used (including the Xfinity Speed Test ) or the selected end-point servers selected.  This started around June 28, 2018.  Test results are now much slower than I've ever seen over the last few months when testing eastbound.

 

However, results up and down the extreme west coast remain normal.

 

Could some fellow users on the east coast possibly please be so kind as to help me out by performing some reverse flow speed tests toward the west coast and maybe overseas?

 

We only have two fully updated Windows PCs within our 20-year-old single family home which connect via ethernet Cat6 to a 1G Router with it's wireless disabled permanently  ... no mobile devices other than non-Smart cell phones.

 

My Netgear CM600 is within normal range DS signal strength on all channels and all 24 are bonded (-6.9dB or higher) and 40+SNRs.   No extrodinary levels of Correcteds and zero Uncorrectables being logged.

 

Have also tried direct connecting to the Netgear CM600 (bypassing the router) and also temporarily disabled the firewall and A/V to no avail.  UPDATE: ALSO TESTED BYPASSING THE HOUSE ENTIRELY BY MOVING TWO PCs TO THE GARAGE AND CONNECTING THE MODEM AND TESTING WITH AND W/O THE ROUTER AS DESCRIBED IN LATER POSTING ..... NO CHANGE.

 

These results below from Portland, OR are usually a bit higher in the middle of the night, but prior to June 28th all the eastern locations were always at least a steady 100/12 even during rush hours

 

Portland ........    423/12 @ 6ms

Vancouver BC . 442/12@16ms

Seattle ..........    404/12 @ 8ms

San Jose ........  384/12 @26ms

Denver ...........     64/12 @46ms (Used to get 200/12 w/similar Latency)

Chicago ........      64/12 @64ms (Used to get 180/12 w/similar Latency)

DC ...................    24/11 @84ms (Used to get 110/12 w/similar Latency)

Atlanta ............     23/8   @86ms (Used to get 100/12 w/similar Latency)

Miami .............    21/11  @94ms (Used to get 90/12 w/similar Latency)

Tokyo ..............    12/8    @176ms

 

The latencies appear to be normal but it almost seems like there has been an electronic barrier created at the Rockies to throttle traffic that flows from the far west coast to the east coast, and maybe even the other way west somewhere across the Pacific Ocean in my situation, based on the Tokyo results ... sounds silly, I know.

 

Thanks for the help folks!

I did some of the same speed tests from South FL on my Extreme 250 plan (was 150 but got updated a few weeks ago to 250). I'm getting pretty much the same speeds on the east coast and west cost.

Thanks very much for your results to Tokyo and Vancouver BC around 6pm PT:

 

Tokyo:            299/24 @ 243ms

Vancouver:    302/24 @ 100ms

 

Seems like we have the same latencies across the U.S. but I'm going to open a Tech Support Ticket as to why my west to east tests are so much lower than yours going the other direction from east to west.

 

Last question .... please confirm the modem you are using?  Thank you.

I'm also using a Netgear CM600 modem. My signal levels:

Re: West to East Speed Tests Very Slow Now at all Times of the Day and Night

Thanks for your CM600 status ..... Wow, looks like you've got more than 15dB of additional DS signal strength than me. 

 

I have about a 100 foot U/G drop from the street pedastal plus another 100 feet of Comcast installed RG6 home runs throughout the home to deal with ... which probably costs me 6dB of DS signal loss alone at the modem frequencies used.  Anyway, here's my CM600 status FWIW.

 

Sure hope some other good folks on the east coast can chime in here with a few tests going out to west coast for comparision.

Try bypassing any splitters you have if any as a test and check for improvements.

Re: West to East Speed Tests Very Slow Now at all Times of the Day and Night

JW .... since I had already tried replacing the splitters the other day, I decided to take your suggestion a step further and removed the entire home's wiring out of the equation.  I moved both PC's into the garage along with the router and CM600 right near the 3rd door at the wall where the outside drop from a conduit enters a box where the combo MoCA/Ground block meets the house wiring.

 

So tonight using one of two Comcast provided 10 foot RG6 Coax cables made up by the last Tech who visited here 8 years ago with the proper threaded connectors, I connected it to the combo MoCA/Grn block and ran it around the corner just into the garage as shown in one of the photos .... no TV and no Phone splitters at all .... just pure Comcast.

 

To make a long story short, I see a 11dB increase in signal strength at the modem's frequencies ginving me about +4.0 instead of almost -7.0dB on the CM600's status page when used in the house normally.  Thus I presume we have around +4.0dB at those frequencies arriving at my ground block to the house..

 

However I don't think low DS power is creating the issue that I described in my original posting. That issue persists even in the Garage w/o the house wiring being part of the equation .... both tests where at the same time of day around 9pm ET/6pm PT and the same 80F dry weather.   Normal speeds of 300/12 to 480/12up and down the extreme west coast servers and very low speeds like 25/12 when testing east coast or even midwest severs.  Not much improvement hours later with the distant servers like well past 1am ET/10pm PT as I right this posting.

 

This is unlike what I hear from other customers where their speeds are pretty much even cross country to within 25% of their results from their closest server.  In the garage, I tried multiple Cat6 Patch cables, soft booting the CM600, rebooting the router, eliminating the router, and also another 10 footer Coax RG6 from the outside ground block box.

 

What have I missed here?  The normal signal power math for my CM600 in my office room  of nearly -7.0dB properly adds up if one is receiving +4.0dB at the ground block via a nearly 100 foot U/G drop from the street pedastal, then routes thru the  two 2-way splitters .... i.e. one for the TV break-out then the 2nd one  for the Arris phone modem, then thru  100 feet of home-run Comcast installed RG6 inside the house.

 

Obviously more power is not the answer.  Should I have Comcast re-provision my Arris TM822g for HSI?  Although it only has 8 DS channels of course, I routinely got close to its theoretical max of 340/12 from local servers and also well into the 100's or even 200's from the east coast or midwest testing servers.

 

Could I have received a bad provisioning file or maybe my fairly new modem is simply failing?

 

Maybe all the extreme and many wild fires out here in the west are part of the issue at this time?

 

Anyway, here is the setup in the Garage along with a photo showing a typical 24/11 test result to Altanta (among others) plus my CM600 Status from the garage ..... my in house status page was already posted earlier:

Re: West to East Speed Tests Very Slow Now at all Times of the Day and Night

The only reason I suggested the splitters is because I saw your Upstream levels towards border line. I’m actually not sure what else I could say. All of my east coast to west coast tests turn out good and mostly finish at the speed of my tier.

Yes thanks, I noticed that too ..... The 4 dropped back down nicely to 41.5 from 49 w/o any splitters or maybe a combination of no splitters and higher US power levels seen when in the garage.   I tested two computers and they react the same way to the speed tests.  I actually PM'd one of the employees back in May when I got this Modem and it was still slow to the east coast but not as bad and they said that's normal ..... Was only getting 40% of my local server speeds at the time but since June 28th those east coast speeds suddenly tanked.

 

I'll blame it on the fires out here for now .... if I received from my "state of the art" HSI provider just 50% of the day to day reliability I get from my small collection of 45 to 50 year old Detroit Iron muscle cars, then I'd be a happy camper.

Taking a shot in the dark here, try factory resetting the modem. I believe it is a 30-60 seconds press and hold of the reset button on the back of the modem. Its not a provisioning problem since you can still get your speed locally.

Thanks .... I would have responded sooner but all HSI in my area when down shortly after I posted my last message last night .... How ironic as it happend  just minutes after making that last quip about being a happy camper if I had HSI only 50% as reliable as my old car collection.

 

TV and Phone were unaffected.  I called Tech Support and the recording said they are working on it and hope to have things back within 6 to 8 hours .... since I don't use Smart Phones I unfortunately  missed some lucrative trading opportunities when the U.S. markets opened.

 

I actually tried the full hard CM600 Factory Reset (hold reset for 7 seconds) and went to bed around midnight .    Spent about an hour on the phone around 9am this morning with the Provisioning Tech who  finally treated it as a new modem after trying many things and got things working again.

 

Nice part is that now I get the full speeds to the east coast using both IPv6 and IPv4 like other  users.

 

Must  have been a partially corrupted initial provisioning back in May.   We'll see how things go for a few weeks before I declare the issue closed .... Thanks again for the help.

Re: West to East Speed Tests Very Slow Now at all Times of the Day and Night

Correction .... Make that time on the phone a total of 2 hrs and 45 min (from 9:00am to 11:30am PT) between the two Techs working to re-provision the factory reset CM600 plus having me try different things and different computers, etc .... I lost track of time and thought it was only about one hour.  However, my Xfinity Connect Voice page with a log of all my calls shows otherwise.  Fortunately I have the separate Phone Modem, so thankfully I did not need to use a cell phone .... in a very weak cell area, no less.
