Usually N-routers work in so called the compatibility mode which allows users with g and sometimes b wireless cards to connect to it.
Yes, however, your internet speed will only be that of the G router which is comparably slower than that of an N router.
Yes.
Any laptop manufactured during the past five to ten years will have an 802.11 b, g, or n wireless interface. Any standard 802.11 b/g/n wireless router will work with any b/g/n laptop, but you may wish to use your computer's Device Manager to see which type your laptop has since you may not want to buy a more expensive 802.11n router if your laptop can only use 802.11b speeds.
Yes, it will be able to connect to your B network however it will only run at the B speed. If you want to take advantage of the 802.11n speeds you will need to upgrade the router.
A Wireless N router simply uses different types of Hardware, the exact piece is called a N Connector. This allows for the router to not only put out a wireless signal, but it also allows for the router to receive wireless signal. This works great for computers that cannot pick up wireless signals normally.
N Routers are a type of broadband router and is a member of a large and diverse utility and application family of wireless broadband routers. You would use these for your broadband needs and may be an upgrade or be the product you are seeking to upgrade in improving performance.
Every computer can be wireless with the purchase of 2 items. The router as stated and now a usb wireless adapter. Both can be purchased for less than $150 and will give you coverage in and around your residence. Recommended purchase is the Range max N router from liksys or comparable "N" type router and usb adapters.
If you are currently using G then step up to N and also make sure to buy a wireless N receiver for your computer or the router is useless. If you are currently using G then step up to N and also make sure to buy a wireless N receiver for your computer or the router is useless.
N access point/router is an overkill for home applications unless internal home network has several (~5+) computers, which exchange a lot of data. Speed of a G WiFi network is already much higher than a typical cable or DSL Internet link so upgrading to N WiFi is pointless if Internet speed access is the only consideration.
To use advantages of N type network you need to have both devices of N type.
There is no significant advantage, you would need a wireless networking card on the expresscard slot, usb port, or on the internal mini-pci express slots.
Yes, it'll work, but only at G speeds (50mbps) as opposed to N speeds (200+). Both wireless standards use 2.4ghz as a radio frequency, which is why they'll communicate - the difference is that N devices also broadcast a 5ghz signal as well. When overlapped, both frequencies increase signal and range. When you setup your router, go to the router admin panel and make sure the mode is set to Mixed - if you set it to G only you might have a problem with signal strength or speed. My advice (and I'm a computer & network consultant) is to take your g router back and get an N router. The speed difference is a lot, especially if you're doing any online gaming or media streaming. If you are, consider going to Dual-Band N, which essentially gives you 2 network channels in one system. DBN allows you to access both the 5 and 2.4ghz channels individually, so you can prioritize data on either one. For example, if you've ever noticed how your connection slows down if you have family members downloading at the same time, you could put their systems on one frequency band and have priority data that you use/access broadcast over the other band. Your regular N card in your laptop won't allow you to access both bands - you need a DBN adapter for that if you get a DBN router. But it's worth it if you access a lot of media streaming on the 'net.
