I posted in another topic, but want to bump this one to the top to see if anyone got around this problem. I have a SpeedStream 5260 modem and a Linksys BEFSR41 router. My connection drops occasionally and I have to power the modem off & back on to get the Linksys to reconnect via PPPoE. Occasionally I will see the same problem with the "network connection unplugged" message in Windows XP. The confusing part is this problem is fairly new. It's only been happening the last month or so, and I've had my DSL service for over two years with no problems using the same modem & router.

Did anyone else find the cause of this problem?]]> http://www.dslreports.com/forum/remark,11072058 Mon, 16 Aug 2004 22:11:11 EDT Re: SBC-DSL + router = dropped connections http://www.dslreports.com/forum/remark,10692877 dragger : I'm getting the same behavior here. I posted a message last week and only got one reply, from a user who was having the same problem.

I have excellent speed when I'm connected, but I'm experiencing 1 to 4 drops daily according to my monitor log.

I'm using my original 5360 (forgot to ask for a new model when I renewed to Expert Plus in Feb) and a Linksys BEFSR41, both about 14 months old.

I hate to bother the techs over in support, but it doesn't appear anyone here has any suggestions for a problem that seems to be hitting more than a few users lately.]]> http://www.dslreports.com/forum/remark,10692877 Mon, 05 Jul 2004 11:15:42 EDT Re: SBC-DSL + router = dropped connections http://www.dslreports.com/forum/remark,10664678 slowazhell : Just moved to OK from Chicago and had DSL there.

I may keep my eyes open for another modem at Staples, any suggestions or things to beware of? I'm currently using a 5262 Extended Reach version through a Linksys BEFSX41 Cable\DSL Firewall Router.

Try it straight without the router, if it does the same thing, then it might be wiring problem or a problem in the Central Office. Basically, sounds like ASI may need to get involved to check things out. If the connection stays solid without the router, then you might've found the problem.

It's happened again several times in the last hour or so. I'm collecting information via my SonicWall log file. I've watched the modem lose it a couple of times, but the router always reconnects. I did have to recycle the router once because it couldn't re-establish a PPPoE connection. I'm not suspecting the SonicWall is the problem at this point, but I'll collect some more information, and if that proves useless, I'll bypass the router, and see if the problem goes away.
I won't be able to live without printer for more than a day, though, and it's only connected via the network. I'll have to reconfigure IP's to test connection without router, so I'm considering that a last resort.
I'll attach my sonicwall log as it stands right now, for amusement. If the times can be checked against network information at ASI, maybe a correlation can be made.

UPDATE: As of this morning, my PPPoE connection was lost 7 times in the last 8 hours. Updated log file attached. Increase in frequency in the early hours of this morning.
Now THAT's what I call a dynamic IP address!

You've had DSL for 3 years....have you had the Modem that long too? If so, possible the modem is going bad. Other than that...not sure. Is your modem near anything that could cause electrical interference( the usual tier1 stuff).

Had my original 5260 when I noticed the pattern, so I dug out the unopened box with the 5360 in it (from last service upgrade) and got exactly the same thing. Everything else seems to be the same. I'm noticing, in addition to random drops, a few times a day when the speed goes to nearly nothing for a while, then gradually comes back. I'm collecting data via line quality, ping, and speed tests.
Maybe SBC is working in my area, and the tech support folks I've talked to are just unaware.

There is no way for any sbc equipment to tell what you are using to auth with it is all PPPoE.

I would definitely consider replacing it ...

If you are currently at the end of your SBC contract
and start a new contract, you can get another FREE modem
just by asking for it. Unfortunately, you can only get
the modem FREE at contract renewal time. Any other
time, you'll be charged $99 for the modem.

(Or to put that in plain English, SBC will allow you
one FREE modem per yearly contract)

If you are currently in the middle of your contract and
outside of warranty, your best bet might be to go to
someplace like Micro Center, Best Buy, or CompUSA to
pickup a new modem. You can often find a DSL modem
there for less than SBC's $99 price tag and often
better modems too!]]> http://www.dslreports.com/forum/remark,10640088 Tue, 29 Jun 2004 10:54:45 EDT Re: SBC-DSL + router = dropped connections http://www.dslreports.com/forum/remark,10639190 Frohike :

I spent a bit of time on the phone with linksys the other day (switching ports, switching cables etc.). The only thing I havent done is upgrade the firmware.

pardon my ignorance, but what is 'NIC'

Thanks for your help :)]]> http://www.dslreports.com/forum/remark,10633016 Mon, 28 Jun 2004 16:50:13 EDT Re: SBC-DSL + router = dropped connections http://www.dslreports.com/forum/remark,10632951 DaSneaky1D : SBC doesn't support 3rd party networking equipment. Your problem is more than likely related to your NIC droping the connection with your router, or your router having a bad port.

Try moving the LAN cable to a different port and see what happens. If you still see drops, you may want to upgrade the firmware on your router. If that doesn't help, please post back. You may even want to look at the Linksys forum for help there!

SBC, though, is not the cause of this issue.

I bought a Linksys WRT54GS wireless router and set it up on my PC (Windows XP). I am able to get it running, but after 5-10 minutes my connection will get dropped. I see the 'network cable unplugged' message pop up on my monitor (though nothing has been disconnected). I then have to go back and eventually reconnect.

I have SBC-Yahoo DSL and have heard that SBC doesnt like you to use any routers other than the ones they will sell you and therefore make it difficult for you to do the networking on your own. Has anyone had this problem and solved it? (or can point me in the direction of a solution)
