On my replaced Wifi router, I noticed that there is a choice to make regarding the frequency distribution.
- 802.11g network that run at 2.4 GHz.
- 802.11a network that runs at 5.0 GHz.
Does the Quality of Service get affected by selecting different frequencies? I read both supports up to 54 Mb/s, so max bandwidth might be irrelevant. So why would you run a 5 Ghz network frequency?
Also, I noted that some cordless phones runs at 2.4 Ghz, defining one of Cisco's rules - keep away the Wifi router from devices like those. Most Wifi routers do run at 2.4 Ghz, but if there is interference, and you are too lazy to move the router, would you really go and spend the money on a 5 Ghz - supported router?
