Weird problem with Optimum Online cable, technician says it's on MY END!?

Well, here's what my problem is. I'm on a 3com CMX cable modem on Optimum Online here in Connecticut. Whenever I stress my connection with newsgroup downloads, which use a lot of bandwidth since it is from a local server, then my connection will freeze. I still have cable modem power and status lights on, and a PC link status light meaning my NIC is getting a connection. However, the activity lights will be off for this period of 20 seconds while the connection is dropped. I called my Optimum Online (Cablevision) and they sent a very arrogant tech out here today. He examined the cable line coming off the splitter and said the signal was way low. He moved the cable modem line to the 3.5db slot on the splitter and that upped the signal a lot, and said this should fix the problem since the modem was only getting just enough signal to operate. I then went and stressed the connection for him and it dropped once again. He then proceeded to tell me that it was an INTERNAL problem with my system/network card and that he will have to send a higher tech out to fix it and it will cost in upwards of $130. I told him that I would have to troubleshoot it since I don't have that kind of money to blow, so I would give them a call back.

After he left, I decided to try and figure it out myself. My current system is:

Iwill KK266
AMD Thunderbird 1ghz@1ghz
512mb Crucial PC133 CAS2
Hercules Prophet II MX
Sound Blaster Live X-Gamer
Netgear FA310TX NIC

I went ahead and stressed the connection with newsgroups until it dropped. When this happened, my modem still had a PC link status light on, but no internet activity lights. My NIC had a status light on, but no activity. 20 seconds later when the connection came back, the activity on the modem and NIC came back on. I shut my system off and threw in an old SMC EtherPower II 10/100 NIC to see if it was the NIC. I did the same procedure, and the connection dropped for 20 seconds and came back on. This obviously means that my system is not at fault, and it is either the modem or service. I need to call them back and they are going to want to send a higher tech out at a cost. What recourse do I have? Anyone know what is going on with my service? I don't have $130+ for a tech that is going to open my system up and swap network cards, and possibly damage my system due to possible lack of knowledge. Thanks in advance, any advice is appreciated.

oh that sucked.. whats his tech number, i was the old supervisor.. i'm in greenwich with another firm now, not doing that optonline crap///

are you in a house or apartment ... how are you wired from the tap (pole) to ur house/apartment/room. how many splitter do you have..

if you can see the tap, do you know how many ports are on the tap, too many people = bad

also is ur ground properly grounded...

on the tech ticket, did you write down the signal level ? if so, the 500+ ones, 582 or 627, is it positive or negative..



try to ping yahoo.com with -t in a dos window and try to connect and see if it drops stuff while your doing that or not..

forcesho:

I am beginning to believe it may perhaps be internal with my system. I am running Windows 2000 with a bunch of the patches over at speedguide.net. I just tried to replicate the problem on my brother's Win98 box and I couldn't get it to drop the connection. I am going to try and remove the speed patches to see if that is hindering it.

Deleting those speed patches seemed to have fixed it. It's weird because I have them on the Win98 box but it didn't drop.

I was using all of the TCPWindowSIZE patches, etc that are listed under the Windows 2000 section.

Viny,

Those patches increase the size of the TCP/IP window on your machine. You can send out X packets before you need an ack. If the windows is set to high, you will end up waiting a little too long for acks and this may be your problem.

I thought 2000 was pretty well setup for broadband connections already?

Windows 2000 is already tweaked out with TCP/IP. With the speed patches, I got about 600-1000k/sec off of newsgroup downloads. Without them, I get around 500-700k/sec.
