Wierd prob - activity light

[audscott]

I've done a good deal of searching & haven't seen anything addressing my prob:

Stats - surfboard 4100, Netgeat FA310, duality WinXP/98 SE, Athlon processor, GeForce card 256 MB memory.

Last week I replaced AT&T's SB3100 with my own 4100. Yes, I had an AT&T tech do it.

After provisioning I couldn't get a connection. I got the usual run around about dual boot, but the phone tech was good enough to give me some insights.

Well, finally got my connection, but with the activity light in full blaze. If I do a power cycle, it ceases for a while, then starts back up. Updated netgear drivers, diployed speed fix - same deal.

WinXP (beta 2) is my primary OS - it has a built in fire wall, which is enabled.

Anyone have any suggestions? Possible the modem is defective? (or is it just me? )

Thanks for the links.

I had searched "activity light" before posting.

Here's a more detailed look at the wierdness: I power cycle -leaving the modem unplugged from power & the RC connector for 10 minutes. Turn off computer and completely disconnect power.

Reonnected modem power & connector & boot.

It'll work as it should for between 10 minutes to 3 hours. No activity light other than when data is being transferred. Throughput scores are good and pages load fast - I'm happy!!

Then inexplicably the activity light will come on. I check networking status & see no data is coming or going. Bandwidth is unimpeded.

Guess I'll just leve well enough alone. AT&T has tod me this is normal, and although I know it's a crock, I have a transcript of this from the tech as well as a 3 year warranty on the modem...so I'm thinking I'm covered.

Just wanted to see if anyone else had encountered the prob!

I'm good as gold.

Usually when the activity light goes crazy like that for me, its because somebody is funning an invasive port scan on my system.

Also, if you are using an internet sharing program and allowing it to be a DNS server with a real world IP address or a Private IP address that your Internet provider uses, then your are causing traffic to be routed to you rather than to the servers it was intended for. This is a violation of service, if it is happening, because something on your computer, if this was happening, is causeing a traffic failure on the ISP internet system.

If you do use something to share an internet connection, what IP addresses are you using.

If you see similar addresses on the ISP's infrastructur, have you tried usine different private IP addresses for your internal network, say rather than 10.xxx.xxx.xxx numbers, try the 172.16.xxx.xxx numbers or the 192.xxx.xxxx.xxx numbering scheme.

Yes I did have that same problem, after many many complaints to the cable company they replaced my modem and I haven't had that problem sence. the tech told me it was a problem with the modem itself. don't make sence to me, but replaceing it solved the problem, so I am happy.

Well, I did another looooooooooooong power cycle leaving tghe modem off, unplugged and unloved for an hour....oh the humanity LOL

Seems to have worked so far - couple of big file transfers and system up for 18 hours without the wierdness returning.

Everyone keep you fingers crossed.

when the light is flashing constantly for you all is it slowing down web page surfing and your download and upload speeds? and what about your ping times during all this?

If it's really decreasing all this then you know for sure data is being sent or recieved

but if it does not reduce performance it might just be what others have suggessted, the nature of a shared medium on cable......

Well Brent, That is all true in all normal conditions, In my case the consenent activitity light at times even after a push by the @home ISP and even after unpluging the modem turned out to be the Modem.
