Recently, Im constantly losing internet connection after a cut cable was replaced. What might solve this?

Had TW Cable here in Westminster Ca rerun a line from the street some 100 yds away from my house into my garage...from there a threaded connector sends it 30 ft outside to ground on the electric box and returns it to the RF input on a SV A15 PRS4 subscriber amplifier provided by TW. 3 numbered outputs send cable to a set top decoder box for digital cable, a tv with basic cable and another tv with basic cable. The 4th output is labeled RF OUT/DC IN and has the HSD cable going to the RCA cable modem. All outputs are labeled 7.5 dB.

Why might I be losing connection at the PC constantly? There are no issues with any of the TVs.

I can get the connection back each time by unplugging the modem and letting it reboot, but it's annoying.

The TW tech said the signal is -2dB at the street hub, which he said is low, they accept nothing lower than -3dB.

What can I have them do now?

I tested speeds in Nov at 9000+ DL and now it's only 5500+.

Thanks for any help.

What can I have them do now?You can have them FIX IT !! :eek:

Who cares what the level is at the hub. They have to provide correct levels at your service entrance!

I may be wrong, but wanted to mention it anyway...

We had much the same problem last year and I always blamed the cable service, too...BUT we found out it was actually the modem itself. Got a new modem and hooked it up and everything has been fine since.

Just a thought...

Just a suggestion when you get the modem working again, access the diagnostic screen and check the downstream power.

Unfortunately, I do not know how to do that.

Is that through Device Manager?

If your modem is made by Motorola (e.g. SurfBoard), this URLwill take you to the diagnostics section:

http://192.168.100.1/

Click on the "Signal" page and look for the dowstream and upstream levels. Ideally the downstream power level should be a positive number betwen zero dBmV and +15dBmV, although they generally work OK in the -15 to +15 range. The upstram power should be less than about +50dBmV, high 30's to high 40's typical. The modem will put out as much power as needed to make the upstream link work, but it can't make more than about +55. If either downstream is too low and/or upstream is too high, inform TWC and ask for a service call to troubleshoot.

Other brand modems may use a different IP address, but it will likely be in the 192.168.x.x range.

Hope that helps...

I'm with replacing the cablemodem first. This is rudimentary troubleshooting. :)

Why isn't this TW Cable's problem?? Why are you farting around ... just call them!

I got a new modem from TW and it's still dropping connections.

Have called TW numerous times and they've done diagnostic tests over the phone and state that the connection is there.

Currently, they have me disconnecting the wireless router and running the ethernet cable straight to the desktop to see if the connection is going to drop that way.

They are supposed to come back out on Sat.

The only difference from the previous (when working well) setup that I notice (novice here) is that there used to be a bunch of TW slpitters and now there are none.

The street cable goes to a ground and feeds into an amp now, there amp has 4 outlets, one goes to the modem, one to the digital box and the two others to tvs. There is one outlet that is not capped...is that a problem.

Is it a problem to not have the modem line prior to the amp?

I think I reaad these issues somewhere else.
