Default Introducing a wireless G device to wireless N network

If you have a wireless N network (with wireless N adaptors all around) and introduce a wireless G device to the network... will the network slow down to the speed of the wireless G (forcing all machines on the network to run at wireless G speeds), or will the signal being transmitted by the router allow both the G and N devices to run at max speed?

This can not be answered in 25 words or less.

There are many ways to implement mixed b/g/n networks. The network will be somewhat slower than a pure n network with most possible modes, and the network will slow to g speeds when the g client is active. It will not slow everything down to g speeds all the time.

not a good choice for VoWiFi, the shifting of gears screws up timing and degrades audio quality.

I had this same basic question - pretty much. I have a Cable Modem > Wireless N Router > Wireless G Router..... My laptop's built in Wifi card runs at B speeds, so I use it to connect to the Wireless G router. The other computers in the house are connected to the N Router. Is this a good workaround to keep the N router from running at B speed?

b,g and n use different modulation methods. like AM, FM and SSB, but different.

these modulation methods use the same frequencies, but can't hear each other. the radio has to switch between modulation methods to see if another method is trying to talk to it. the switching back and forty takes time, the listening takes time. the different modulation methods on the same channel cause collisions, which waste time.

keep n on a different channel from b and g. let the b device connect to a g router and hard wire the g router to the n router.

I have been thinking of trying this last recommendation. Does it really work to hardwire the two wireless routers, one N and one G, together, and then to assign different channels to each N and G laptop? Seems like the ISP's modem would get confused between the two routers. Or is it all automatic? I wouldn't mind just trying it but sometimes this can screw up all the settings that exist, couldn't it?
