Frequent loss of internet
Have had problems with my internet of the last couple weeks.
Typically, resetting everything, i.e. cable modem and router, will temporarily fix it, just to have it go down an hour or more later. Cox came out and within 10 seconds of entering my home and putting the coax cable in his tester, said signals are good. He suggested I replace my cable modem. I did, and I still have problems.
My signal page has the following levels:
|Acquire Downstream Channel||837000000 Hz||Locked|
|Downstream Bonded Channels|
|1||QAM256||837000000 Hz||5.8 dBmV||40.5 dB||69||0|
|2||QAM256||843000000 Hz||6.4 dBmV||40.8 dB||38||0|
|3||QAM256||849000000 Hz||6.0 dBmV||40.7 dB||117||0|
|4||QAM256||855000000 Hz||6.9 dBmV||40.8 dB||102||0|
|5||QAM256||885000000 Hz||7.1 dBmV||40.8 dB||307||21|

|Upstream Bonded Channels|
|Channel||US Channel Type||Symbol Rate||Frequency||Power|
|1||ATDMA||2560 Ksym/sec||38900000 Hz||49.5 dBmV|
|2||ATDMA||2560 Ksym/sec||22600000 Hz||49.5 dBmV|
|3||ATDMA||5120 Ksym/sec||27500000 Hz||49.5 dBmV|
|4||ATDMA||5120 Ksym/sec||34000000 Hz||
When I log into the modem, the upstream power is ALWAYS 49+, with usually 50+db. Cox says this is good, but I do not agree.I will also log in and see the modem only will bond to one upstream channel.
I replaced my cable modem, but with the newer cable modem (Surfboard SB6141) had even higher upstream Db than the one it replaced (Zoom 5341J). Seeing as the new modem didn't fix it, I put my Zoom back online.
I restored my router (ASUS RT-N66U) to default firmware as well, no difference.
