Details on Wireless N Router range on G Adapters?
Hi guys, I googled for plenty of time and can't seem to find similar topic with desired details. These questions assumed that G Adapters (and only G) are connected to N Router:
1. Will N Router helps to extend the range? I am aware that the speed wont, but what about range/coverage? Some said it has to be with N adapter, some said it will, and the others were not sure. I have this great answer from jpcloud, confirm/deny?
===========
Yes. The 802.11n standard includes a new antenna configuration over the older g and b standards, meaning that the transmission range and reception sensitivity of the router will be greater than a b or g router. However, while a computer with a g or b network card will have a greater range when connected to an n router than it would when connected to a g or b router, it will still not have the same range as an n card connected to an n router. This is because the n network cards contain the new antenna configuration, which gives them longer range, while the older cards retain the older configuration. Therefore, for an n router and an n card, you have two factors that extend range, while for a g card connected to an n router there is only one factor that extends the range.
Edit: To DaveEC, your answer neglects the fact that N design routers also have increased antenna strength, and so they can detect a weaker g or b signal (lower signal-to-noise ratio) than a g or b router. This does in fact increase the range of a g or b card when connected to the router, but not to the extent of an n card on an n router.
================
2. If #1 answer is yes, will this extended range apply if wireless signal is set to B/G only (not Mixed N/B/G)?
2 questions above aside, but still under same assumption:
3. Will G clients have connection disturbances with mixed N/B/G signal compared to B/G or G signal?
Thanks in advance.

1. G adapters run in G mode, and the router does "G" protocol with them. In effect, you are running in G mode only, and have no benefit from anything related to "N" modes in the router.If you only have a G adapter, no need to get a N router unless you plan to upgrade your adapters to N in the near future...
While N routers may have slightly better semiconductors (newer), the increase in sensitivity for G or B modes would probably be minor at best. Even then, if there is any interference nearby, a better receiver and antenna will simply increase the interference level as well...
Antennas for some N routers are exactly the same, if it's running on the 2.4Ghz band. Only if you have a 5.8Ghz N router and adapter, would you see improvement in signal strength, antenna gain (usually), and less interference.
