arris SB-6190, intermittent connection failure
hi folks, I'm kinda at my wit's end with this issue, but here's the low-down:
* i'm a cox ultimate internet subscriber
* last week, no internet, so i call up cox tech support, am told that it's probably my older modem went on the fritz to get a new one
* i purchase an arris sb-6190, call tech support back up to get it provide mac addr, get it provisioned, etc
* internet still not working, discover that there's actually a system-level outtage in my area and it's resolved some 25 hours later.
* discover that due to my "ultimate" package, old modem wasn't gonna work so must forge ahead with new sb-6190
* things are mostly OK, but getting persistent lossy outbound connections and seemingly dropped data, particularily in gaming
* do lots of digging online and discovers there's lots of things in play here, people having problems with SB-6190 due to Puma chipset and buggy firmware
* my particular SB-6190 firmware version is 9.1.93V (the latest) and that probably fixed prior issues
* I'm still having those same connection problems
At this point I'm quite stuck so I poke around on the SB-6190 status console (http://192.168.100.1/cgi-bin/status), armed with the arris support docs at http://arris.force.com/consumers/articles/General_FAQs/SB6190-Cable-Signal-Levels, and they are:
| Upstream Bonded Channels | ||||||
|---|---|---|---|---|---|---|
| Channel | Lock Status | US Channel Type | Channel ID | Symbol Rate | Frequency | Power |
| 1 | Locked | ATDMA | 3 | 5120 kSym/s | 29.80 MHz | 39.50 dBmV |
| 2 | Locked | ATDMA | 4 | 5120 kSym/s | 36.30 MHz | 41.00 dBmV |
| 3 | Locked | ATDMA | 2 | 5120 kSym/s | 23.30 MHz | 38.00 dBmV |
| 4 | Locked | ATDMA | 1 | 2560 kSym/s | 18.40 MHz | 37.50 dBmV |
A few things I notice:
* arris recommends for 4+ channels ATDMA channels should have 5120 kSyms/s, in my case channel 1 is not this way
* arris also recommends minimum power levels of 45+ dBmV and all mine are below that
Does anybody think this could be the culprit for my issues or is there something else I should be doing? Calling tech support has been a harrowing experience as most of the operators are addressing things at such a trivial level where if I bring up the concept of checking power levels they ask me to clear my browser cookies. Ugh. Any help/suggestions/things-to-try would be great
