For several days now I have encountered a problem with my DSL where the connection just goes away for anywhere from a few seconds to a few minutes. It happens (on average) several times an HOUR. I've done all the usual tech support steps (and tried to call today but was forcibly disconnected because when they routed me to High Speen Internet support they just said no one was answering -- goodbye! CLICK) and nothing helps.
I replicate this both directly connecting a laptop to the Ethernet connection out of the DSL modem (an ancient Westell 6100 with ancient firmware -- not even the Verizon firmware but the old blue and white interface) -- and through the wireless connection, so my wireless router is clearly not the problem. Either there are known problems at the source (mine comes out of San Angelo, TX I believe), my wiring is iffy or the ancient modem is starting to fail.
It's up right now, here are the transceiver stats:
|Transceiver Revision: 22.214.171.124|
|Vendor ID Code: 4|
|Line Mode: ADSL2+ Mode|
|Data Path: Fast|
|Transceiver Information||Down Stream Path||Up Stream Path|
|DSL Speed (Kbits/Sec)||3355||695|
|Line Attenuation (dB)||21.5||8.5|
|Transmit Power (dBm)||21.8||12.1|
The Up Stream Path speed varies a lot -- anywhere from 300 Kbps to over 800 Kbps, but the downstream is pretty steady at 3355 Kbps. IN fact, the DSL connection keeps dropping on me while I'm trying to submit this!
Unless DSLAM congestion could possibly cause upstream sync issues, I doubt that is the problem. It look more like your upstream has a problem that should be fixed. Might want to try a NID test to see if you can get that margin to at least 10dB and also make sure you can get the sync to 864kbps as well. If you can't achieve that get Verizon out to fix the line.
