Ok, I am having a lot of trouble with Comcast dropping my connection for days at a time it seems. I am just writing this to “bounce some ideas around and see what others may think..
The cable modem I had hooked up the day I for it within 2 or 3 minutes, though even after repeated calls to Comcast, it never seemed to “activated” … then at midnight (about 5 and a half hours after I started), it sudden worked
My Routers (I will get the model numbers later, but I have three that work fine for the LAN and worked great for about a week and a half (no touching the wires) ….. now no matter which one I hook up (and wait a few minutes of course), none work with the CM. (The Modem seems to work and the routers work … its when they are put together (and yes I did change the CM to Router CAT5 cable, with no luck), they start fighting)
I have one Wireless/Wired Netgear, and a Wired only Linksys and a similar Linksys only with wireless too. (**** All the connections to the net I am trying to do are Wired only... this is not a “wireless issue” question)
(I believe it's called a D3 modem.... I see the people with 1.1 or 2.0 “Should upgrade” … just to put that out there)
OK
My setup
Wall to splitter (which I even changed, “just to try another splitter”) then one goes out to the TV and the other to the CM. The ENTIRE setup was fine for about a week and a half to two weeks (as I think I said).. Now the only way to get blue lights (meaning connected) with the “Ready Green Light” on too is directly connecting the Coax from the wall to the CM. THOUGH even then the CM goes out again when the (any of them) router's would get involved.
I have REPEATEDLY (lost track … near 50 times) done the reset “method” (turn off PC, then unplug router, then CM …. wait … then plug them all back in)... even if it connects … its only for roughly two minutes and then the CM Upstream light flashes again.
I have unplugged and replugged (even tried Wall ~~> Amplifier (though that doesn't really fix the problem anyway.... and it didn't, so it doesn't matter) ) so many times I have lost track now.
I have repeatedly hit reset on the CM for 30 seconds and waited … same thing as before … even if it worked it connects for 20 seconds to two minutes, and then its out again.
I have even done the same on the routers (which seem fine, but I am willing to try it).... all reset does is eventually make me have to reset my router PW's but it doesn't fix the issue.
I have switched every coax cable and even though I have a ton already, I used the Comcast only cables, bypassing everything I have and meaning despite paying for it I have no Cable TV … THAT doesn't help the modem going out all the time now.
I am at my wits-end and somehow got it to work long enough to post (Wall to CM and router reset again... but now I have no TV) and may call a tech (despite not having high hopes) after the holidays ... I just dont understand why it'd work perfectly for 2 weeks or so and then just cut out. and one more thing ... "Check the coax cables to make sure they are ' snug' " ... Thats the FIRST thing I tried.
Thanks to anyone (Comcast or just other users) with feedback .... I just have a feeling this is on "Comcast's end" and not even sure if the CM is faulty ... I think the level (this is getting to the stuff even I am not really sure about) of the signal is fluxerating ... long before this, I found on some TV's I need to go from (before Comcast Internet) I needed to go from WALL to COAX AMP to Digtial box to TV ... or I would get pixalated (always during a show I liked) video and dropped audio ... the TV is ok with the amp, but I stil get no "CM fix" when going from wall to AMP to CM (which again I have read doesn't actually fix the signal... it justs boosts the bad signal, I think)
anyway Thank you again
