Internet speed slowing down - modem?
Taco.22:
We are on ADSL broadband, running a Billion 7700N modem/router. We run two ethernet and three wireless devices. Over the last couple of months our internet speeds have slowly dropped from about 300+Kbps to between 8 and 120Kbps, mostly 30 to 40. I rang our ISP and in the end they suggested it might be the modem. I have done various isolation tests and swapped cables and filters. I have done the reset and reconfigure a number of times. With the ISP on the phone we actually lost internet because the Quick-start kept missing the page for user-name and password. Eventually, some time later, I got the config to scan properly and reconnect. Still slow!!
We are in the process of finding another modem to test and compare - should be a spare one we can borrow where my wife works. In the meantime, does anyone have any experience of this, and particularly that model. Our ISP mentioned that a number of other customers have had issues with Billion modems of late. At least we still have internet after the scare yesterday, but by rights it should really be up around the 800Kbps mark.

Hi,
Maybe the content of a traceroute or tracepath to some remote ip would help your ISP figure out the problem? Here we have had some problems of disconnect when we moved in, but that was frequent disconnection problems, not slowness. And the problem was a damaged connecting sleeve on the line which was used as a house by a few families of insects happily enjoying an environment of dead leaves and such.

You should check out the line quality. Most of the routers have in their web interface a place where you could see this information.
Look up for CRC and FEC, the higher the number of CRC and FEC, the higher the number of packets transmitted are errors and error corrections. It slows down the transmission and gives this sensation you 're running an IP over avian carriers network.

Thanks for the responses. It would be nice if the modem just issued smoke and sparks, because that would be nice and straightforward!! We borrowed another modem from someone using the same ISP, so it was just a case of plugging it in. According to the Speed Test our download speeds jumped to 1.2Mbps, real life download was about 500-800Kbps, and we could stream youtube and online TV at high speed. After an hour of this we figured we needed a new modem and swapped back to our crappy one. Guess what?!?
Our modem now does everything the test modem did!! We have had three computers streaming at the same time, upload and download at the same time, do basic downloads and browse - all seems to be maintaining the higher speeds. I rang the ISP and explained the testing procedure and results and they still think it's the modem - something to do with repowering. I'm at a slight loss because the Billion is still under warranty and we were going to speak to the supplier. Might still do. In the meantime we can get a free inhouse-designed modem from the ISP, so that's an option as well. Means we can do direct comparisons for no extra outlay and we would have two modems, just in case.
I didn't realise there was so much to modems. We will keep an eye on the current one and see how it goes, but if it does what it did before it will be a gradual decline in speed.

Because you got him jalous. He thought you were replacing it. :D

The power of will... joking here. The chipset might have been too hot?

How long has it been running at your home since you got it?

ie: in case of a thunderstorm which breaks it you can have a fast replacement.

Or just dye suddenly. :)
Good get anyway, you have the connection at the right speed back and new ideas around the issue.
