Random Modem Reboots

I've been experiencing sporadic modem reboots for about two months now. I assumed the Motorola SB5101 SURFboard
cable modem and/or Cisco Linksys WRT54GL Wireless-G router was starting to malfunction so I went to Best Buy and
purchased a NETGEAR N300 Model No. C3000 WiFi Cable Modem Router Combo. to replace the previous setup. I had the
modem/router activated over the phone and the connection initially seemed fine. Everything went smoothly. A day
later the same modem reset issues happened on the brand new setup and have not stopped since. To clarify: These
resets are completely random. Time of day or weather conditions do not affect this at all.

I have done some research and noticed the upstream power levels on all four of the bonded channels suddenly spike
from the normal 46dBmV to the ridiculous and unacceptable 54dBmV+. I have seen the upstream power level on my
modem go as high as 60dBmV on one of these "spikes". My modem is basically "screaming" to get its signal heard at
very sudden, random points in time. The problem is that when the upstream power level spikes like this, the modem
immediately resets itself, reacquires the signal, and spits out a bunch of T3/T4 Timeouts while it is at it.
This, of course, causes a loss of connection that I cannot have since I stream and use real-time applications all
the time. Any disconnection is extremely frusterating, even if its only for a moment. I even have family members
who don't use the internet the way I do (i.e. Surfing the web.) that comment on how a webpage isn't loading for
them when they try to load one up during a "spike".

I have called COX twice about this issue. The person on the other end of the line acknowledged that my modem was
resetting extremely often and commented that that was very unusual. He said everything was showing up OKAY on his
end. Said person decided to schedule a tech visit to identify and solve the problem. The tech arrives and
investigates. He tells me that everything is looking OKAY on the line and tested it with his own battery powered
modem for a total of THREE MINUTES. I understand the tech has a schedule to keep, but in order to catch something
like this, I think there has to be a test like that done for a LONG time in order to see when the upstream power
level RANDOMLY "spikes." Naturally, the tech says everything is fine other than the fittings on one of the cables
which he replaced. He told me he "thinks" that will solve the issue I was having, but was unable to guarantee
anything. During the whole time he was there the modem did not reset and was working fine(of course). I tried to
explain to him what was going on like I am doing now in this post, but he seemed to almost ignore me. The issue
continued to persist.

I then call COX again and the new person on the other end of the line acknowledged that my modem was indeed
resetting very often and scheduled a tech visit the next day. This tech seemed more knowledgeable, but was still
unable to identify and solve the issue I am still having. The modem did not act up while he was here, but the
funny part is about a half hour after he leaves, the modem decides to reset! I again tried explaining to him what
I thought was happening as I am doing in this post and he acknowledged what I was saying, but did not say or do
anything about it. This tech tested the modem by connecting to my WiFi through his tablet and doing random google
searches to confirm that the internet is working fine. This did not test anything relevant AT ALL and wouldn't
even have a chance to indentify the issue unless he tried loading a webpage at the EXACT time of the "spike"
happening. The tech basically gave up and told me to "monitor" it for 72 hours and to try calling again if the
issue is still there.

The issue is, of course, still there because no action was ever taken in the two phone calls and two tech visits
I've had. I have not bothered to call again because that is getting nowhere. Instead I decided to reach out on
the forums here and see if any COX employee can understand what I am trying to tell them and take some sort of
action so we can see some progress. Signal levels will be at the end of ths post. I don't mean to be
insulting, but if a tech is sent out again, please make sure he is informed about my situation somehow and knows
"what's up". Any help at all from anyone on here would be great. Thanks.
