Dlink BCM96358 (From my ISP Telus)"
My ISP is Telus.
Where are you located ?
There is no info about that model on the Telus web site I use.
How old is it ?
It probably connects to the internet via your telephone line, and it's some type of ADSL connection.
Gong by my experiences with several high speed modems, and combo high speed modem / routers provided by Telus, since I first connected to the internet via a high speed ADSL connection in early 2001, your problems are most likely due to there being electric or electronic line noise being picked up on the telephone line that is interfering with the internet connection.
If you pick up a phone on the same phone line when you're having problems, you may hear a staticy noise, or you may hear that only while you're using the phone, however, it isn't necessarily within your human hearing range.
Certain software can test your internet connection to see whether it's dropping a larger number than average of data packets - that's a sure indication you have a line noise problem.
In my case, I live in a neighborhood that has telephone lines on poles in the back alley that were probably installed in 1959 and have probably never been replaced since. I tend to have more problems with line noise during and after rain storms or thunderstorms, but it can happen at any time.
It's been happening lately with my Actiontec combo high speed modem / wireless N router that is also supplying our Optic digital TV service. Sometimes both the TV signal connection and the internet connection fails to connect, but it's the internet connection that's poor a lot more often.
For info about what you can do to reduce line noise in / at your own residence.....
See Response 7:
You can test your connection speed on the web to confirm whether it's poor or not, at any particular time.
E.g. I choose the same test and the same closest server (in Canada) to my location here, for comparison purposes:
It really isn't important whether you get the max speed possible, although it should be in the ballpark of what it's supposed to be for the package you're paying for (the max speed will vary depending on which web site you choose that has a speed test, which server you choose if you can choose from more than one, how busy the server is at the time) - it's more important whether it has changed drastically, for the same speed test on the same web site with the same server.
(I get the highest speeds with the Text + Shuttle test with a server located in Canada, which is where I am.)
Note that if you do the same speed test again within a really short time, subsequent tests may yield a falsely higher rating because files that were downloaded to test with are still in the Windows page (swap) file on your computer or in it's memory. Do something else for a few minutes before you do the same test again for a truer rating.
NOTE that the high speed modem of your combo high speed modem / router will probably NOT reset itself to a better internet connection when the problem has gone away that caused the connection to become poor.
You usually MUST "reboot" the device to get a better internet connection again - I do this FREQUENTLY.
To do that while the computer is running, if the high speed modem, or the combo high speed modem / router
- has a power switch, switch it off, switch it on.
- has no power switch, either
- unplug the DC connection from your device on the back of the device - pull on the plug, NOT the cord - plug it back in.
- or - unplug the AC connection on the other end of the AC to DC adapter's connection - pull on the plug, NOT the cord - plug it back in.
In either case, WAIT until the leds light up on the front of the device that indicate you have a working internet connection.
That usually takes no more than two minutes or so, unless you have a BAD line noise problem at the time.
Other things that can be wrong ?
If you DO NOT have your high speed modem, or combo high speed modem / router, plugged into something that protects it against damage cause by power spikes or power surges, most likely to be experienced during a power failure event, the device may have been damaged. My first high speed modem was probably damaged by that during a lightning storm.
If you have had the Dlink BCM96358 for a long time, if you contact Telus, they may supply a newer model free of charge.
