Internet speeds slow down significantly after initial connection to the RG

Hello All,

 

I'm having an issue with my Internet speeds.  Let me give you some background.  I have uverse TV and Internet.  I have fiber running to my house.  The house is wired via Ethernet, which is how the connection is coming in from the box outside.  I have the 18MB plan.  Upon first connecting to the network via Wifi or Ethernet, I have excellent speeds.  My ping is less than 30ms and the download is about 17Mbps.  The connection progressively comes to a crawl.  Using speedtest.net, I see my speeds fluctuate between .9Mbps to 17Mbps and somewhere in between.  My ping times can get as high as 700ms.  Once the speeds go down, they stay slower than 13Mbps for the majority of the time.  AT&T came out to replace the RG.  That didn't help.  They came out to replace the box on the side of the house.  That didn't help.  Even the AT&T tech had the same issues on his iPad.  What else could the problem be?  I'm at a loss and don't know what to do.  Thanks for your help.

Re: Internet speeds slow down significantly after initial connection to the RG

Having FTTH (Fiber to the Home) eliminates a great number of potential issues.  Having Cat 5e or better home wiring eliminates some potential weirdness you get from Coax.

 

Let me ask this:

1) Are these speed reductions visible both on wired connections to the RG as well as wireless connections to the RG?

2) Are you aware that IPTV will consume part of your 25/3 profile (at approximately 6 Mbps per HD stream viewed or recorded, 2 Mbps per SD stream), so that you will not have the full 18 Mbps available when watching or recording two or more HD streams?

3) Are you running any P2P, online backup or online game which distributes patches via P2P, such that your upstream bandwidth might be getting saturated?

4) Is there anything you can do that does bring up the speeds again?  Reboot PC?  Reboot RG?

5) How many devices do you have using the Internet connection?

Re: Internet speeds slow down significantly after initial connection to the RG

1. Yes

2. TV is not running or recording when this is happening.

3. No

4. The only thing that gets it to boost is to reestablish a connection.  For example, I unplug Ethernet and turn on Wireless.  It's normal speed.  Then it slows down.  Then I turn off wirelsess and plugin Ethernet.  It's fast at first and then it slows down.

5. It happens with 1 or multiple devices connected.

For grins and giggles, the next time you see signficant issues, take your browser to http://192.168.1.254/ (Your RG) and navigate to Settings, then diagnostics.  On my router this is:

 

http://192.168.1.254/xslt?PAGE=C_5_5

 

Scroll down to this section:

 

Current NAT Sessions

current secs since boot: 10419467
session table 906/1024 available, 0/512 used in inbound sessions:

 

The coloring is mine for reference.  Let's see if your session tables are full.  If the number I made green is low (under a 100) or the number in red is large (over 500), then this may indicate some issue.

 

Post back here and let us know.

It looks to be normal. I don't think the RG is the problem since the new one is performing exactly the same as the one it replaced.

That report wasn't so much to find a hardware problem with the RG, but to see if you're experiencing a particular resource limitation with the software (which would be the same for all RGs).  But, you're not.

 

I'm out of things to check.  Maybe someone else has an idea to offer.

Re: Internet speeds slow down significantly after initial connection to the RG

OK - I will come up with a wild and crazy solution. Aren't 18 and 24 two levels of service that compete with the TV for bandwidth - Hence Jeffer's question are the TVs on? Even though the answer was no, there could be something wrong with that circuit in the RG. But, it is the same an a new RG. The new one has the same problem.

Another possibility is incompatibility with the FTTH architecture. I say this based on the TV service offering once (now?) being less than copper service.

This problem has been resolved.  AT&T social media support was awesome.  The problem was with the optical network terminal on the side of the house.  The software on that needed to be updated.  Now it works as it should.

Re: Internet speeds slow down significantly after initial connection to the RG

Btw, the issue was more than likely an RJ45 end that was assembled incorrectly, therefore you had crossed pairs going to the RG, seems to be an issue, since the feed from the ONT (Optical Netowrk Terminal) to the RG is an ethernet cable into the RED broadband port. Making an ethernet cable can be a hassle if you haven't had alot of practice doing it hence it happens quite alot.
