Cox → Weird intenet connection problem

I am in Irvine, CA and have a weird problem since this past Thurs... I am keep losing internet connection after about half hour connection. I can get it back by either power cycle the router, or go into the router (Linksys WRT54g with tomato firmware) and release/renew the connection. When I check the signal level at 192.168.100.1, downstream is -5.5 dBmV and SNR of 37.8 dB. Upstream is 49.2 dBmV.
I have tried different routers (an ASUS 520 and a Netgear WNR3500L) and they behavior the same. When I called tech support, the first tech said the cable modem was configured for static IP and he went ahead to reset the modem. After couple of hours, I ran into the same problem and called tech support. The 2nd tech support said I should either replace the cable from the wall to the cable modem or take the router out of loop. Since I have replace the router couple of times and the cable between modem to router, I don't see take the router out of the loop will do anything. Is there something else I can check before calling again.
Thanks.

Make sure connections are tight, lose any splitters you don't need.
if you run anything like BIT TORRENT that makes lots of connections, consumer level routers don't handle lots of connections very well.

when you are losing connectivity and you log into your router are you seeing a WAN IP address listed? If so, once you reboot the router or release/renew is the WAN IP still the same IP as it was before?

Will have to remember to write down the IP address before I do release/renew.
I have bittorrent running but the # of connections are set to 50 and the configuration has not changed for months. As a test, I have shut down the torrent client but the problem still happen. Will check the cable today.
Thanks.

update: get rid of one splitter I don't need. Now my signal is improved to

downstream 0.0 dBmV/ 38.4 dB
upstream 42.9 dBmV

It just acted up. When I did release/renew, I got a new IP address.

About how long is it between times when your service is good and it starts to misbehave?

Very random. Last night, one last about 15 minutes. I reset it around 10 PM last night and I didn't have to do anything until about half hours ago. Not much happen during the night but I accessed the web in the morning on and off.

This is just a guess, but it sounds like your ISP may be low on IP addresses in your market. A lot of times when an ISP gets low they will set lease times to very short intervals so that a maximum number of users can get on for a short period of time and surf/check email/etc... then another user can get on and do what they need to do. You could call and ask your local office, but the person in the office might not know what's going on or in some cases they won't admit to the problem. Again, I can't guarantee this is what's happening, but it's what it sounds like.

If there is the case, I would think other would have reported here as well but I don't see others are having the same issues.

It is going crazy now. Each connect last less than 10 minutes and each renew get me a new IP address. I even got couple starts with 184.179.xxx.xxx

Hi, I'm also in Irvine CA. I was just looking through threads on this forum and I'm having this exact same issue. My signal values are pretty close to yours (all seem to be within specs). It's been happening for the last few days. My public IP address changes more often than usual after resetting all equipment. The issue happens less at night (around 11pm to sunrise) and mostly during the afternoon to late afternoon. Cox has sent someone to check the physical cables and those seem to check out. So I was just wondering if you've been able to solve the issue? Thanks!

No, the problem is still here. Internet access can be lost even no or very little activities are going on. The last connect lasted less than 30 minutes when only one laptop is powered on and its lid closed!

sorry, double posted

I'm considering replacing my modem. Hoping that might do something to solve the issue?

how old is your modem? Mine is a Linksys that has been in used for about 5 yrs.

those levels are now VERY GOOD!

But now I experience more disconnections than when the signal level is not that good. Can this be an issue with the cable modem?

My modem is also about 5 years old.

Does this issue persist with the router OUT OF THE LOOP?
if it does, your modem might be dying.

I'm also in Irvine, CA and am experiencing the same issue as well. Best as I can tell from my dealings with tech support Cox is aware of the problem and is working to resolve it. It's not a problem with your equipment. Not much to be done at this point other than wait for Cox to fix their stuff.

When I called Sat, tech support did not give any indication that there is a problem at their end. Will you get notification when the problem is resolved?

I got a call from someone at Cox late in the afternoon on Sunday who acknowledged that they had found a problem on their end. They also claimed the problem had been fixed though... so I'm not counting on them calling back when the problem really is fixed.

There was an issue in one of the California markets yesterday which was indeed resolved so your issue may be unrelated at this point.

Right before noon today, I replaced the Linksys WRT54g with my Netgear WNR3500L (the one I have been using for several months) thinking the problem has been resolved since no disconnection occurred this morning. The first connection lasted about 6 minutes, 2nd connection lasted abut 10 minutes. I switched back to the Linksys WRT54g just now to see if that makes any difference.

update 1: connection just lost. Lasted less than 30 minutes.
update 2: connection lost after 20 minutes.

"Some Cox Communications Internet customers in Orange County report they have been without service most of the three-day Presidents Day weekend.

There's some major construction along Jeffery on the north end of Irvine. I bet somebody didn't call before they dug.

Everything seems to be running ok so far today. Hopefully everything stays running. Thanks everyone for the help and updates!

Things are looking good. I switched back to my Netgear router about 4.5 hrs ago and have no disconnection so far.

Just got back from work and my connection is working fine now. Looks like they got things straitened out.

Hi Stringy!!!
