A couple of weeks ago, my DSL service went down. I caled DSLx. The tested my line and my modem was talking to the DSLAM but no packets were getting throught verizon's servers to DSLx. They called verizon and had it fixed in a few hours. The problem was somewhere upstream of the DSLAM.
As a backup, I used me personal iPhone as a hotspot. T-mobile gives unlimited data though they slow things down once you use your allotments of 4G. But even 2G is faster than my DSL.
Had it been anyother day, I would have walked to Starbucks or the public library for Wifi, but I was doing a radio sow tha day. That meant I needed a quiet room so I used the phone as a hotspo and the landline phone for audio.
A week or so ago, Grandpa told me how he loves DSL. "DSL is great," he said.
But there's a downside. He saw an increase of $10 a month in his electric bill, which he attributes to the DSL modem being powered all the time. I told him that he canunplug it, but he should power it up before booting his computer. that willgive the modem time to sync to the network before the computer is ready.
When the speed drops, Verizon sends a technican to check tim line and it shows full speed but that's during the day. I tell them to come back at 9PM and try again.
Last time, the tech told me that my lne can supprt 7mbit DSL if I want it. I then told him to call his central office and have them move me to another DSL port. that was around 6 PM so speed was still up. They switched me to a new port in about 15 minutes and since then, I've fall full speed 24 hours. Measured speed is about 2.75 mbit/s.
dslextreme.com is my ISP. You have to sign up for a year to get the $15/month rate. Otherwise it's $25 or $30/month. I pay $30/month for 3Mbit/s. I could to the 5mb or 7mb for another $20/mo but don;t need the extra speed. We run Netflix all the time.
You could say the exact same thing about wifi, "I have an idea, let's send standard ethernet packets over 2.4 ghz garbage band, we don't need carrier protection or division access schemes, we'll just use sense and retry!". When you first start working on it, you're amazed it works at all, and looking back I feel like a caveman trying to launch the space shuttle by building it a large bonfire as an offering.
Netflix transmits at 1.5 MB/s. Contact Netflix to see if you can get a higher data rate. Also, if you are using WIFI, you may want to find a channel that is not used a lot in your immediate area.
I had similar problems but couldn't get the telco to fix it. I was having slowdowns and disconnects on DSL. I could fix the problem temporarily by going outside to the telco box on the outside of the house where I'd unplug the line then plug it back in. I suspect it was a bad connection in the box but since a phone plugged into the outlet on the box worked, they wanted to charge me to come out and fix the "inside wiring".
I'm wondering now if this was another manafestation of a problem with the DSLAMS although I could hear the noise on the phone line when the problem occured.
I switched to cable which has been more reliable although the price keeps going up...
