Wi-fi g+n — is it possible?

Question

WiFi

As far as I know, at the moment the use of wireless access points based on 802.11 is possible either only in g mode (as an option - b + g), or in n mode. But a situation arose when it was necessary to use two standards at the same time, due to the fact that both support for old devices and the use of a network at a decent distance from the location of the access point are required.

Question 1: Are there solutions on the market that solve this problem?
Question 2: Does anyone have experience using two adapters at the same time, but in different modes and in close proximity to each other?

PS: you also need a USB port on the router itself (one of them) to connect the hard drive and raise the torrent client later using it as storage.

Answer 1

In 2.4GHz mode, 802.11n is backward compatible with 802.11b/g.

Answer 2

1 Yes
2 Netgear has good home solutions with USB

Answer 3

1. I have a Dlink 825 (G + N) everything works fine
2. Mac (N) + Lenovo S10 (G) + iPhone (G) + Lenovo T400 (N) is connected to it at the same time - everything works, nothing conflicts
