I found all posts reguarding this same problem and did the suggested pinging of google and ipconfig commands. Below are my results. I noticed I am getting 100% packet loss, is this a bad gateway?

I am on a pc running win xp with a DSL wireless plan with AT&T Uverse. My pc is cabled and not wireless.

Modify or edit binary?

So if I lose connection again after changing the NodeType does that mean it is the 2 wire gateway modem that is the problem?
 
Not necessarily; Create a NEW FILE and insert
  • ping 8.8.8.8
  • ping google.com
Save As NETPING.BAT

Anytime you question your connection;
  • launch CMD
  • then enter netping.bat
The PING 8.8.8.8 with good results timings says you ARE connected to your ISP

The ping to Google with good results says your DNS is OK too.

You are a genius jobeard !! So far I have not lost connection since that HEX 8 I changed. I am fascinated by this stuff. What did I change when I did that? What does that command basically do? Where do I put that BAT file?
 
If you use IPCONFIG /ALL you will see (near the top) that the Node Type was Broadcast and is now Hybrid.

We're directly changing how DHCP is being process, but there may be special cases like timeouts that get addressed also.

Put the BAT file into your c:\Users\yourLogin\ directory. Anytime you need it you can get a command prompt and invoke it literally like
.\NETPING.BAT

Awsome jo, Thank you very much. So far still no connection loss. It was happening at least 6 times a day for the past 6 days. You are my hero ;)

I spoke too soon. The moment the lease renewed on my connection I lost connection. Below is the result of

ping 0.0.0.0
ipconfig/release
ipconfig/renew
ping google.com
restarting gateway
ping 0.0.0.0
I ultimately had to reboot to reconnect

Stay wired - - more secure and faster that WiFI.

Do you have access to the router login? we can tweek some things there.
 
OK Yesterday I called ATT and a tech came out and replaced my gateway. This one is a Pace model 5268AC. I stayed hard wired on my desktop PC. Before leaving he said an inside line test revealed a lot of errors and could be my problem. He said all the line tests outside were fine. When I asked what line and how do I fix that. He shrugged his shoulders as if he didnt know. So, sure enough, this morning I lost connection again. Do you know what "line test" he is talking about and how I can fix it? And yes I have access to the router login and I do not mind tweeking, keeping in mind my wireless items lol ;)

Would the phone cable from the wall outlet to the gateway be the issue? His line tests were running from an ap on his phone. Is there a desktop version of a "line tester"?

Yes that can be a problem. Get a new, short rj11 phone line & move the modem as close as possible; use a longer rj45 cable to the pc, the modem will crease better signal reliability. When we have wired reliable connections, we move on to wifi

Move the modem as close as possible? To the wall jack or PC? Right now it is 4 feet from wall jack to modem using a 8 foot rj11 and 8 feet from modem to PC using a 16 foot rj45.
Another thing I noticed is the wifi is not lit up on the modem but the ethernet and broadband 1 is. We pay for a wireless connection. Shouldn't the wifi be lit too? I am not having an issue with the wireless so I guess it doesnt really matter? lol
 
Rj45 is fine, replace rj11 with 3ft if possible. If wired is unreliable, then so will wifi - I promise. I'm on my tablet just now and have other info to send you
 
U-Verse and the 5268AC are both 'marginal'; help desk and tech services are reported by many to be ineffective.

Here's a link to the User's Guide:
but as to a complete manual, there seems to be none :sigh:

I found this >> "How can I update the firmware for the 5268ac?"
which gave the answer:
  • "A factory reset by Holding the reset button for 15 seconds is supposed to download the latest software version"
apparently the latest version is "10.5.3.527171-att" but I don't see where/how to get the version from the device. Other routers report the version when you login, so give that a try and see what's on the first page shown after login.

no - think about it. the tech is on sight w/o a pc so he needs a portable device in his bag. These are professional devices, not easy to find and would be expensive to buy.
said there were line errors inside

geographically, where are you locate and are you in a single family home or a multifamily building? The latter are very difficult to work with.

The router page shows Software Version 10.5.3.527171-att. So thats a match.Thank you for the above link. He did not leave anything with me about it.

The "professional device" he was using was his android phone. When I asked about the line test he said "Oh I have it right here on my phone, let me show you". Which did me no good since he couldntor wouldnt explain what I was looking at and which line.

I am in a 3 unit apartment top floor.

The factory reset button I am very familiar with seeing as that is how I keep having to regain connection for my pcand now the wireless laptop. I have replaced the rj11 and now waiting to see if it happens again. If it does I am going to unplug the gateway and take it to ATT and shove it where the sun does not shine on some exec there. LOLOL Damn I needed that laugh.
 
You can improve reliability by changing the MTU in the router to 1492 or lower (must be by intervals of 8). If you find it at 1500, then change it, else leave it alone. The value should be seen on the WAN side settings.

Before I go any further can it be my ethernet card going out? All cables are new plus modem and still losing connection. The restart and or reset of modem does not reconnect me only rebooting pc works? Is there a way to test it? Multimeter? CPUG?
 
Not modem issue. The PC is failing when the modem+router initiates a release/renew cycle - - VERY common.
  1. find the make+model of your NIC card (also the WiFi )
  2. access the manufacture's website and look for Downloads, Firmware or Drivers
  3. make sure you know which version of Windows you're running, eg Mine is Win/7 Pro sp2 64bit
  4. then down load the correct driver (from 1) for your system (3)
  5. look for install instructions on the page -OR- within the unpacked download
  6. to the install
