Good Afternoon

For about the past 2 months I've been having some serious issues with my cable isp. The majority of the time my connection works perfectly, other times my connection is quite intermittent. By this I mean one second my connection will be working strong, and other times it won't work at all. I've opened 3 tickets with my isp, now on my fourth for the same problem but they never seem to find anything wrong.

Today it stopped working again until now, Tech support always tells me to unplug the modem for about a minute or two to bring it online again. This genrally works but when it does not the send/receive light will flash as though preparing to come online and than the online light will begin flashing red.

Tech support will not support linux in any way so I setup the modem on my XP box alone and it did the same thing for almost an hour, but now it works. My usual setup is, isp-->cable-modem-->eth0-->eth1 to my hub which has a linux, XP, and 98 machine connected. I've kept an eye on my logs but am unable to find any sort of error, also on the third ticket I opened the techs came in and installed brand new cables and also replaced my newer terayon modem with an older model.

If anyone has had similar issues or possibly knows of a fix I't would be greatly appreciated.

This problem is most likely with your ISP, they just don't know it yet. some solutions I tried:

The problem is with your modem, from what i read it looks like it.

The modem might be passively cooled, this means it has no fan to cool it down and it gets too hot, try placing it some where with lots of ventilation (near a fan). Try another modem, borrow one from a friend to check your connection. Take your modem to your friends house to test your modem with his connection.

Check your wires around the house:

Make sure all your wires are not bent, peeled, or the insulation is cut.
Make sure that your CAT-5 is the correct length (Too long will cause problems).
Make sure that wires are not passing under or below anything that might give out
extreme temperatures, or frequencies.
If you recently installed a cable splitter make sure that is connected correctly.

The problem might be in your residence:

If you live in an apartment building talk to the neighbors,
if they are having problems, ask them to complain to your ISP.

The problem might be in your neighborhood:

Go out to other buildings / houses and talk to your other neighbors,
if they are having problems, ask them to complain to your ISP.

Other:

The cable company is making repairs around your area and they haven't informed the ISP people because they are different "departments". Look around and see if you can spot a cable repair truck, if you see one, call the ISP (and cable company) and ask them to check if they are making scheduled maintenance (that might affect internet service).

If you have a "bargain" ISP, they lease the lines and support from the local cable company, if this is the case, you will have to wait for them to hear about the problem from a third party before you get any real answers or help.

Last: Ask your ISP to replace the modem (again), and give you credit for lost time ($5 off next month's bill?).

It seems that u don't know the basics of internet.Try reading online manuals
