Turning Speedstream 4100 Modem (ON and OFF)

No one (so far) seems to know - is it harmful (to the modem) to turn it off when internet is not needed? My internet provider (At&T/Yahoo)cautions me to leave it on all the time - "as it may shorten the modem's lifespan to turn it on and off." The modem has an on/off switch on the back - and I would prefer to turn it off when not needed, for two reasons: It gets hot (to the touch) when on and I'm not able to keep my computer in sleep mode when the modem is on. If anyone has an expert opinion on this matter, please advise me. Thanks.....Lee Anders

    8th Wonder,
    Thanks for the response. 1) As to the heat generated by the modem, do you feel that constitutes a fire danger if left 'on' all the time? 2) By not being able to place the computer into 'standby' (while the modem is on), the hard drive is running during the times the computer is not being used. Which do you suppose would cause more damage over time, letting the hard drive constantly run, or turning the modem off during idle times - and back on when internet is required. As before, I will appreciate any information you may care to share with me regarding this matter. Thanks.....Lee Anders

    8th Wonder,

    Many thanks for your advice. I have, from another website helpline, found the solution to my problem - as follow: go to My Documents - right click My Computer - click Properties - click Hardware - click Device Manager - click Network Adaptors - click Realtek - click Power Management - UNCHECK "Allow this device to bring computer out of standby" So far, this action appears to be working. Perhaps this information may be of use to others experiencing the same problem. Lee Anders

First thing is all electronics items are made up of ICs, registors and capacitors. What will happen if you strecth and release a rubber band 100 times in 5 minutes?. it may break or will break very soon. on the other hand what will happen if you strecth another rubber band and leave it strecthd for 5 minutes?. no change will be there in the rubbers tensility. So is the case with every electronic items. when they heat they expand and when they cool they shrink to original. so if you swith on and off your modem the components will expand a little with heat and when u switch off modem the components will come to original position. if this process is repeated daily twice or thrice then i dont think that your modem may be working fine till next year. so let it on for the whole day and switch it off only when u sleep at night if required., thanks.

    See man the modem may not be costly neither the hdd may be costly.. else the hdd will be in huge warranty. the costly thing is ur data,. on hdd. so dont let your hdd suffer for the sake off yuour modem. so think it and decide what to save . you can save either of it. 2. keep the modem on floor or on metal surface away from burnable things if your fear of fire. in my life i have never heard such catching fire. ok

I just bought a SpeedStream 4100 modem

if you brought the wireless new from a vendor. you don't need to configure it. unless you want to.
but if you brought a used one (in you case). you have to configure it. You need to get inside (software wise) of the modem. to do that you need login name and password to start with. if you don't have it, please call or e-mail the guy you brought the modem from.
then you have to configure the security for the wireless, unless you want everyone under sun to access your modem via wireless.
search on the web, you should come away with a user manual for the unit.
