Seems like any time I open my torrent client it craps out. Lately it's begun to reset just browsing...

Am I looking at a bad modem or a signal issue?

Thanks...

The signal levels all appear to be fine. Does this happen if you don't have a torrent running? It's possible that your torrent client is flooding the modem with too many connections.

Seems to only happen with my torrent client open, it used to handle it fine. This just started recently. Could a firmware update remedy this?

If not, it's no big deal since I don't use BT all that much any more. I was just making sure everything else seemed ok.

Thx for the reply, I've been really happy with the uptime and speeds with you guys.

I have a Scientific Atlantic cable modem and for the last couple weeks I've been experiencing the same thing. Really ever since the statewide outage a couple weeks ago here in AZ. Makes me wonder if they are intentionally killing BT users connection. I even had cox roll a truck, everything checked out, they pushed a new firmware to my cable modem, but still getting frequent disconnects.

Found out what was causing my disconnects. I usually don't use bit torrent, but I have been using it to snag some older stuff not available on the ng's. Well turns out cox has some sort of software that disconnects you if your using bit torrent. Once I turned on forced protocol encryption and unchecked allow incoming legacy connections in µTorrent the disconnects completely stopped.

nope.
reread the press release. its a traffic management system that *prioritizes* traffic somewhere around the cmts. its not the same sandvine fake-tcp-reset method that comcast was found to use. additionally, this management system will not cause your modem to lose synch with the cmts, it is using a class-based weighted fair queue (cbwfq) system to move some traffic in front of other types.

whatever you have read is nothing but pure speculation - as i have been able to achieve ~800kbps throughput steady on well-seeded torrents.

q.

[edit] also, if you would have read the press release, this is only for the two markets in the midwest, arkansas and nebraska (i believe).

Not sure what you talking about, I didn't read this information anywhere, I'm talking real world, if I turn off forced protocol encryption and check allow incoming legacy connections in µTorrent I get disconnected every 10 minutes or so and my cable modem is unable to connect for about 5 minutes even with unplugging and plugging the cable modem back in. When I turn on forced protocol encryption and uncheck allow incoming legacy connections in µTorrent the disconnects completely stop. This is in the Cox Phoenix market.

cox has deployed a traffic management system in the markets listed above. a press release was issued and there was a lengthy conversation regarding its existence and purpose in the cox network on this board. this was (i assumed) was being described.
however, the likelyhood of a hardware box performing the actions that you describe are incredibly slim. because of the requirement of layer2 communication along the hfc network and the cmts, it is difficult to insert any hardware between the cable modem and the cmts - as any active device listening to traffic will contain a layer2 address masking your hfc mac from the modem.
additionally, any device using a remote port span would have to be able to communicate with the cmts and tell it to drop synch with *only* that mac; the probability of which is even smaller.

in order to correlate this, have you done any experimentation and data collection besides your anecdotal evidence? i am not saying that something isnt happening, but i am saying that it more than likely isnt happening for the reasons you are supposing.

again, i am in the phoenix metro market, do torrent occasionally, and have never had any issues.

OP here... Modem is now doing this without any torrent client open. I've noticed it when a device on the network is uploading something ( say a video from the XBOX360 to a site ), and another PC is browsing the internet. The modem should be able to handle that, yet it randomly resets.

Is it time for a new modem?

Re: [VA] SB5120 resets frequently

Yes the modem should be able to handle that. Based on the symptoms you have described I still believe my original diagnosis to be the most plausible, that the modem is getting flooded with more upstream traffic than it can handle possibly due to pending failure or ofther factors.
