That's a good warning, Ed. Even at DSL data rates, you are dealing with data signals in the radio frequency range.
My rule for unshielded cables is "short and sweet is neat". 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Edward R Cole Sent: Monday, December 5, 2016 11:52 PM To: Elecraft Reflector Subject: [Elecraft] OT: Fixing Slow Internet Since we all use the Internet this may be of interest: I bought a new Dell desktop on cyber-monday to be used for general purpose Internet browsing, e-mail, and maintaining my website. Figured the i5-6400 processor a good trade-off of speed vs cost and got 8GB memory and 1TB HD. I intend to keep using my 2008 Dell duo-core with XP32-SP3 for running all radio sw but unplugged from the Internet to isolate it from attack by maleware/virus and the OS would not require updates. Installing a GPS dongle with BktTimeSync (Z2BKT) makes this possible. So the new computer arrived overnight and I began loading my Internet-based programs and most files from the old computer. But starting Friday the e-mail began having trouble connecting for download or uploading and Internet came to a screeching halt (almost). I did some driver updates hoping maybe that was part of the problem. But my other computers and my wife's laptop and Ipad also experienced the same problems? A couple calls to the ISP discovered a mistake in a setup entry on my e-mail client but Internet still not able to find websites like msn.com, google or any site I entered. I ran a speed test and it looked OK for my DSL 3.2MBs for 3.5MBs service and 0.9MBs uploading? So one more call to the ISP and the gal who answered from Tech-help said it looked like we had a bad or shorted cable to our DSL Modem. She asked how long was the cable between phone jack and modem? Well we have moved things over the years so some cables ended up kind of long (we had 25-foot of RJ11 phone wired wrapped up with a tiewrap where a couple feet would suffice. I do not even recall it being so long but replacing it with a short 6-foot RJ11 jumper cured the slow Internet/e-mail issues. Modem is connected with ethernet jumper to router with two cat5e cables running to two separate rooms in the house where my computers and my wife's computer are located. I'm not a computer wonk; RF is my area of strength, so I figured the phone and Internet was kinda like audio stuff. Guess not. My guess with the cable folded into a bundle it had a lot of crosstalk or capacitive coupling which acted like a short at 3.5 MBs. Hope this long story helps anyone who has puzzled why they're Internet acts constipated (of course there may be other issues that can cause these problems). 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubus...@gmail.com ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to r...@elecraft.com ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
