What's the difference between broad band and dual band?
The terms aren't really related to each other. Broadband is a telecom term that describes transmissions beyond the old, low-speed telco frequencies. So by definition, all routers are broadband.
Most new routers are also dual-band, meaning they operate at both the 2.4 Ghz and 5 Ghz frequencies. The 2.4 Ghz frequency band is a bit crowded and on paper provides lower bandwidth. WiFi standards also allow for transmission at 5 Ghz which is theoretically faster but also does not penetrate obstructions or reflect as well as 2.4 Ghz. I shut off the 5 Ghz option on my dual band routers because I've found it more frustrating than anything else. 5 Ghz-capable devices will continue to try to connect and drop off. By disabling 5 Ghz at the router, dual-band capable devices will connect at 2.4 Ghz which in my experience is more reliable in my application.
