A:AnswerYou should not have to get your ISP involved--should be plug and play. If you were changing your modem, yes--the ISP needs the serial number and (or) the MAC address from the modem. The router is after the modem so contacting the ISP should not be necessary--unless something very unusual occurs, but usually adding a router is very easy--be sure and update the firmware and use good security with a strong hard to remember password like FvB$k18tGk&. Just remember to document the password in a convenient place. However, even if you lose the password, you can reset the router to its original condition--but then you have to enter in all the information you added, so a hassle, but a manageable problem to have.
A:AnswerThe technology changes so quickly that you should only replace based on need. Speeds double every few years, so whatever you buy now will quickly be outdated. If you buy based on need, you wont get caught in the constant upgrade cycle.
A:AnswerProbably not unless it is the same model and software version. Backups are generally only good for restoring to the original device. Trying to install on a different one may cause strange behavior or failure. If it loads at all.
A:AnswerThe N600 is a router not a modem. A router works in tandem with a modem. Depending on your ISP you will either have a modem fed by a telephone line (DSL/VDSL service) or a coaxial cable (cable modem service).
A:AnswerNo, Anthony. This Linksys E1200 Wireless-N Router only has the 2.4 GHz radio frequency band. You may check this link for more info: http://www.linksys.com/us/support-article?articleNum=142392.
A:AnswerDepends on how far you are from the router and how many walls/ceilings/floors the signal has to penetrate. If there are many, a more expensive (I.e. More powerful) router will probably solve your problem.
A:AnswerHi. A router is needed for you to have wireless access to all of your devices. You may check out this link for your reference: http://www.linksys.com/us/search?text=router.
A:AnswerYou would still need some sort of an internet connection to use the chromecast.
I have actually had the chromecast hooked up in my car once by turning on wifi tether from my phone, and connecting the chromecast with that and my tablet. Could be a hog if you dont have unlimited data on your mobile carrier. But this is one way around the no internet issue.
A:AnswerHi. You can use a wireless adapter on the other desktop or you can use a powerline kit for this type of setup. Please refer to this link to know more about the Powerline Kit: http://www.linksys.com/ph/support-article?articleNum=135964.
