I have a simple problem and need a solution. I may not have tried hard enough, but I am looking for a quick answer. Power cuts are a reality we live with today in Bangalore and has been so for the last few summers. I use broadband at home and many a time use Skype for conference calls. I have an inverter at home for backup power supply and it takes over when there is a power cut in less than a second. My TV, tube lights etc don't get interrupted at all. But my broadband router is a different story. The time it takes for the power supply to get handed over to the inverter is good enough for the router to reboot and this is super irritating. I need to wait close to a minute before I dial back in and as Murphy would have it, this usually happens when I am expected to be doing the talking on the call.
I called up some UPS companies and they say "No UPS can switch over that fast". I don't get it... its a simple problem and should have a simple solution. I am sure there should be other appliances which are just as power sensitive and critical. How come we don't have a solution for this yet!! All I need is a 1 second battery backup after which the battery can give up and my inverter will take over.
p.s: Sudden motivation is, I was downloading a file for the last 6 hours from rapidshare and needed just 20 mins to complete it, but some BESCOM employee felt like testing my inverter and just did a power flip flop. Result is, my download stopped, can't be resumed and now since I am over my rapidshare limit, can't download for the next few hours!!

Hi Ajay,
I can suggest 2 solutions. If you dont have time and if you are looking for the easy solution (which will cost you), you can go to any computer shop, and buy the least costly UPS. The inverters at our houses cannot switch over so fast, but UPS' (Un-interrupted Power Supply) can. You can get one for around 1K I guess. I dont know whether you get cheaper ones.
If you have enough time and interest, you can try assembling one. You can browse the net for some circuit diagrams, and buy the components from an electrical shop and assemble one. or else most of the electronic shops give you kits which contains custom PCBs. All you need to do is solder. This solution will be cheaper and you wont have to buy a BIG battery. Just see your routers rating. I hope this helped you.
I forgot to mention one thing, many of my friends, including me is facing the same problem. For me, I dont want to go and buy a company UPS just for the modem and want to assemble one on my own. But the only thing I lack is 'time'.. ;)
I have a UPS for my PC and a power cuts does not reboot the PC. The modem is on the mains so have not tried to see if it reboots when fed by the UPS. But, what is good for the PC should be good for the modem. Can try and let you know. If you are planning to buy an UPS look for one that does not beep every few seconds when the power goes off (or at least you shud be able to turn the beeps off). Mine beeps and it's pretty irritating especially if u are on a call!
Another solution : Go for an USB powered DSL router (http://www.zoom.com/products/adsl_overview.html#5510b)
or switch to CDMA-EVDO broadband connection
@dragonfly:
As per specs, the UPS thingy won't work. That is what every "big company" UPS manufacturer told me when I called them. If you know of any UPS that solve my problem, lemme know.
@Prady:
If you are able to verify the modem not rebooting when connected via the UPS, can you tell me the brand of the UPS ? I am not too keen to spend money on a new modem at this point. Also, Who in Bangalore gives real (hi-speed) EVDO connections ? BSNL almost always drop down to pedestrian speeds, at least that is what I heard.
