RE: WiFi weirdness
Once when I was having some reception problems the cable tech (Charter) noticed that I had added several splitters to accommodate some added devices. He pulled them all out and added an 8 channel 0 db (no gain) distribution splitter. So now whatever signal level comes in is what each device gets, with 0 dog biscuits gain above the feeder. With that and the trimming of all excess cable lengths, the inside of my customer access box look very neat and the door shuts easily.

BTW, You need to be sure you have splitters rated for forward and backward data flow since many of the older splitters aren't up to that standard.

Paula, As for your current problem on certain parts of your system, I think you will find it's as Mongo has stated, due to a faulty connection or possibly a partial short circuit on one of the cables. Even a corroded connector or a high resistance short can perform as a diode and radiate hellish levels of RFI.

RE: WiFi weirdness
I by-passed the router and hooked L's desktop directly to the modem. She watched Netflix for several hours without a single hiccup in audio or video. She had been watching it with the wireless and it started skipping. Not as bad, but it was there. My desktop which is still hardwired to the router, is almost impossible to view anything such as video, audio, or viewing large images (like NASA image of the day) or "busy" pages.

I'll make a call to the cable company and have them clean out the box. It needs to be done anyway. I'll see if they'll also take care of the outlet here in the office, even though they didn't install it. I may still get a new router but I'll hold off for now.

Sound good. And that reminds me that my provider, Charter Cable, is offering a modem upgrade for free if I'll do the install. Supposedly the new modem is faster. I currently get 90 Megabits down and 10 up so I may just leave well enough alone. I've been guilty of fixing things until they're broke before.

Good luck with your tech visit. Tell him you're getting intermodulation distortion and spurious RFI radiation and see if his eyes cross.

True dat. A tree of 2 way splitters will attenuate signal leaving the last one in the chain with low level. And it will be a lot neater.

And, yes, RG59 is NG; should be RG6 quad shield.

I still think it's after the cable modem. Since wireless is good, then wired should be good or better. That leaves me to believe possible CAT5e cable problem.

It's pretty obvious you have data leaks when you come home from work and find a huge puddle of 1's and 0's all over the floor.

Or a router problem. Or some kind of RF interference from that box of splitters or something like that as a result of the tech messing with it.

I've been thinking about this and my brain was out to lunch when I was thinking it was the coax cables.

RE: WiFi weirdness
I tried new cable from router to my desktop and from router to the modem. No difference.

I went and got a new router. Figured as long as I didn't take the plastic off and was careful with it, if it didn't fix the problem I could take it back.

It wouldn't connect last night at all. I could connect directly to the modem just fine. I could reconnect the old modem just fine. But the new one wouldn't. Used the support "community" at Belkin and was suggested to factory reset the router. A brand new out of the box router? So I did and it worked. Eventually. Once it finally connected, it has worked fine. On both PCs, Netflix is speeding along. And a page I was having trouble loading is much better.

I'm going to keep the old router as a backup. Never hurts!

And of course still have Charter come out and clean up the box.

I didn't think about this until you mentioned it but I would have connection problems with Linksys routers after they got about a year old. I also had the same problem with the DSL modems. I traced the problem down to the power supplies they use. If you use the old router and it "goes south", feel it and see if it isn't unusually hot.

I've not had good luck with routers lasting, either. Checking the wall wart is a good idea.

In my attic I have a box of old wall warts. It comes in handy and is cheaper than having to buy one every time the need arises.

Huh. No, not that I can remember. The only thing that has been warm when I touched it was the end of the coax cable where it attaches to the modem.
