Speed has drasticly fallen...

Speed has drasticly fallen...

I have had U-Verse Max+ since about 6 months ago and was getting 11Mb down and 1Mb up consistently. I logged on 4 days ago and found the downloads to very slow.  Speedtest.net is showing only 5Mb down and .5 up. My pc is connected to the router through a powerline as the gateway is downstairs, though I don'r see that being the problem since that is how the tech's installed it.  I'd appreciate any help offered.

Re: Speed has drasticly fallen...

It could be that some issue has arisen in your home's eletrical system that is causing the powerline adapters to not be able to pass signal properly.  Or there could be a problem with the powerline adapters themselves.  Do you have anyway to test the speed with a direct connection to the RG?

 

Examples of things that could cause noise issues on your power lines that could interfere with your powerline adapters, or with the RG itself: Large appliances, transformers, CFL, normal flourescent lights, excersize equipment, HVAC, etc.

Re: Speed has drasticly fallen...

I cannot connect directly to the RG as my pc is on a different floor. I checked my service retrains like the thread suggested and there where 3 retrains from dec'12 and one at the start of January, so there are no bugs there. I'm gonna have to borrow a laptop to connect directly to the RG, maybe the powerlines are failing.

Thanks alot

Re: Speed has drasticly fallen...

Three retrains from December 2012?  Your RG has been up for over a year without any significant line issue?  Wow.

 

You might just want to reboot it, just to see if that makes a difference.  You could also unplug each powerline adapter and let them reset.

Re: Speed has drasticly fallen...

My bad I meant Dec '13Smiley Surprised and yeah I tried rebooting the RG but that didn't help at all. I will try unplugging the adapters. I don't remember if they were swapped out when I came back to UV, I was with cable for a few years.

Re: Speed has drasticly fallen...

I am still getting horrible speed and nothing is being done. ATT sent a tech out on 02/05 and he said that it was a problem with their system and that it should correct itself within a day or two. Well it's been 8 counting the weekend and I'm still getting shyte. I'm paying for the Max package which is 12Mbs down and 2Mbs up. This is what I'm getting on Speedtest.net: http://www.speedtest.net/my-result/3304616365

 

Are there any ATT Techs monitoring this site that can help me out?

Re: Speed has drasticly fallen...

I can help you out in one way.  12 Mbps down is paired with 1.5 Mbps up, not 2.0 Mbps.

 

Do you have the ability to run UVrealtime?  If so, please download UV Realtime, install it, run it and post screenshots of the IP/Profile tab, Bitloading tab, Error Table tab, and Coax/HPNA tab.

To post screenshots in the forum, reply to this post and use the Insert/Edit Image button (it looks like a tree) in the post editor. One of us will look at your information and let you know what we think.

Re: Speed has drasticly fallen...

OK I dl'd and ran UVrealtime but it will not connect to my gateway. I tried the auto connect and the manual like it says in the help thread and it tries but it won't connect. Is there something else I can do to show you my connections?

Re: Speed has drasticly fallen...

If your Residential Gateway is not a 3600, 3800 or 3801, then UV Realtime will not work completely.  I think it tries to work with a 5031, but it's not completely successful there, either.  If you have one of those and it's not connecting, it could be that you have multiple adaptors on your PC and the program has selected the wrong one by default, or that you have a software firewall on your PC that is blocking the application.

 

You can still take a browser to 192.168.1.254 and look around for your signal rate and errors page and paste it here.

My gw is a 3801 and as far as I know I only have one network adapter, the Realtek PCIe GBE Family Controller. And the Windows Firewall is the only fw thats active. This is the Broadband Status page on my gateway.

Re: Speed has drasticly fallen...

The 3801 should work with UVRT.  You have a 3801 with Internet only?  That's somewhat strange, but not unworkable.  Your stats give most of what UVRT would, except the bitloading graph.  Let's see here:

 

In the past 6 days (of the 2 weeks your statistics cover) your line has done well.  No retrains, no nasty errors, no ECC errors, and a nominal number of FEC errors.

 

Your raw max line rate is 44Mbps down, which is normally good enough for a 32/5 profile (needed for MaxTurbo).  The profile they've set you up for is the 19/2 profile, which is plenty good enough for 12/1.5 HSIA service.  In short, it really doesn't look like the problem is between the RG and the VRAD, though I'd really like to see if the bitloading graph shows artifacts indicating reflection.  

 

One thing I note is that, assuming I've done my math right, you've passed 26 GB of data upstream in 14.5 days.  That's a fairly decent amount of upstream traffic (in fact, that's about 40 hours of solid full-out transmission), so my next question is do you:

  • use online backup
  • upload a large number of pictures or videos
  • use P2P software (such as bittorrent, etc.)
  • play a game which uses a P2P mechanism to distribute game patches/updates

and would any of these be going on while you're running speed tests?

 

EDIT: I also calculate that you have effectively used about 25% of the total capacity of your download bandwidth over this 14.5 days period.  Double check me on this:

 

1224656301747 bytes divided by (1024 * 1024) to get Mbytes = 1167923 MB

1167923 * 8 bytes/bit to get Mbits = 9343386 Mb

 

12 Mbps * 60 m/s * 60 m/h * 24 h/day * 14.5 days = 37584000 Mb capacity of the line

 

 9343386 Mb / 37584000 Mb = 24.9%

 

Does this surprise you?

Re: Speed has drasticly fallen...

I do upoad pictures/videos at times and also use P2P but not while I'm running speed test. As a matter of fact I haven't done any of that since discovering the slow speeds. And I have phone and tv along with internet service on the 3801. Not sure why so much uploading was done in the 2 week period you noticed.

 

When I left the cable co and joined UVerse I'm not sure if the gave me new power line adapters, could this be the problem? I rebooted them twice when you suggested that before and all green lights lit up, could they be failing? And if so where can I purchase new ones?

Thanks for your help I really appreciate it.

Re: Speed has drasticly fallen...

I don't know whats happened but I checked a speed test and I got 10+ down and 2 up. Maybe the tech they sent out was correct in saying that ATT had some equiptment down and they finally fixed it. I'll watch closely till I'm sure the problem is fixed. Thank you once again for all your help.

Re: Speed has drasticly fallen...

Thank you JefferMC but I have only one more question. Looking at my stats do you think my line would support a faster tier? Say the Max Plus(18mBPS DOWN)?

Re: Speed has drasticly fallen...

To get 18 Mbps HSIA, your current 19/2 profile would need to be upgraded to 25/3.  Your line is currently syncing at 44 Mbps, so I don't see any technical problem with that.  Just so you know, the upstream bandwidth will still be 1.5 Mbps.  44 Mbps should be good enough for the 32/5 profile and 24/3 HSIA.

 

They may not be willing to upgrade your profile without a tech visit, so if you have to have a tech visit for your speed problem, be sure to ask him if he'll okay you to get the 25/3 profile so you can upgrade HSIA.
