Cabling Might Matter for your Cable Modem

post #1 of 10
Thread Starter 
I recently switched out my cheapo coax cable that I had running from the two-way splitter to my cable modem. The cable I ditched didn't have the screw-on ends, just the easy "push in" connectors like this:



I swapped it out with a better made one from Comcast w/the screw-on ends and it seemingly increased my connection speeds. I've never hit anywhere close to 30000+kb/s down before. My up speed is normal.



So if you're bored and looking for something cheap to "upgrade", perhaps upgrading your cables might do the trick?

Yes this definatly will. Make sure your splitter is atleast 1200Mhz as well. The cable honestly is not as important as the splitter.

It was around 22K-25. I don't remember it ever going above 25K.

I'm gonna look into the splitter. It's rated 5-1000 Mhz, -130db.

I just found this one on amazon.com....$20 though.

your old cable was probably not well shielded, it must be thinner than your new one. (most the of the push-in kinds i've seen are cheap and thin)

signal really depends on the length of the cable. gold plated ends doesn't really help, it's all hype. Just use properly shielded cables and the ones that dont rot over time

and splitters loose a lot of signal, i believe its 3.5db per 2 way split and 7+db on 3 way. NEVER use splitters on cable modems, always connect your cable modem to the ground junction if possible (first availble split)

I've done work for TWC. The new splitters you lose very LITTLE signal. Using a splitter is fine, infact you are using one already and you don't even know it. This is why I say use no min of 1200 Mhz. The higher the better, but they can and do get costly. TWC generally gives you as many as you need to get your place running. That is if you have TWC.

Generally TWC puts some kind of mark to the cable they call the "digital cable", normally a white strip velcroed around it. This line generally is either straight from the poll or next in line to the outdoor splitter on your house.

I had a problem with my old apartment, it had all rg-5 cabling. Our modem didn't like it because we also had cable tv and there wasn't enough bandwidth for both. So we were able to trick it by using a foot of rg-6 spliced in and it would work most of the time. So the first thing I did at my new place is run a new rg-6 cable to my modem straight from the first splitter coming into the house.

Oh yes that will make a difference. rg-5 is meant for short distances and not meant for digital tv/cable internet/voip at all.
