would a cable splitter affect internet speeds?

[nageov3t]

I've got a splitter on the outside of my apartment, running cable into my living room and bedroom.

currently, I'm using the hook-up in the living room for tv and the bedroom for internet, but I've been thinking about putting a splitter in the bedroom so that I could watch tv in there as well. I don't really care about picture quality (the tv is an 8 year-old 22" crt and I'll only really be using it to watch the news), but would it affect internet speeds at all?

probobly not...put the splitter in and navigate to your modem statistics page. make sure all the tx / rx signal levels, SNR, etc are within spec.

From a cable technician's stand point (at least for the cable company I work for ALL MODEMS DATA/TELEPHONY must be off the first split)

For my company

SNR - 35dB
Rx - 0dB is perfect
Tx - 40dB is perfect

How splitting works:
Company connection via either an underground PED/Lock Box or an aerial Plant/Tap signal being transferred through this device is the overall dB left in the "pipeline" from the closest amp. || node.

That said say your locked box or PED has a tap value of ch2 +14 | ch90 +16 | ch116 +24 your internet value is based off of the center value which is for High Speed Data (HSD) RG6 has a loss in dB every 100' (-1.5dB per 100') say your total run from the locked box/PED is 100' then your HSD value before your first splitter would technically be +14.5 dB and after your first splitter (2 way splitters are often -3.5dB off each leg of the splitter) +10.5dB and after the second splitter +7dB. Which by my companies standards wouls put your modem within "working" range

If your taps values are lower than this and your flirting with possibly -dB the modem may have difficulty staying in block sync. On that note having to high a signal will also cause problems.

Working values Ch2 from to +9dB/+16dB Usually your analog signals ch2/90
Working values Ch116 from to +15dB/+24dB Usually the digital/HD tiers

Tap ch2 +14 | ch90 +16 | ch116 +24
1st split (-3.5dB) ch2 +10.5 | ch90 +12.5 | ch116 +24
