This is because Wi-Fi routers that support 5 GHz Wi-Fi can be configured in multiple different ways. These routers can host both a 2.4 GHz and 5 GHz network at once, which is useful for older devices that only support 2.4 GHz, or larger areas where devices might move out of 5 GHz range but still be within 2.4 GHz range. 2. Set up 5GHz as instructed by your router's user manual. 3. Connect your computer and mobile device to the 5GHz band of your set-up router, and your computer and mobile device will have better speed, better characterization, and better screen sharing when connected to the same WiFi network and using 5GHz. (compared to 2.4 GHz WiFi network) Also, check your phone features to see if 5GHz is supported or not. Many routers have this option to disable and enable the 5GHz band. Step 1: Open Settings in your Android app. Step 2: Go to WiFi and then click on three dots. Step 3: Click on the Advanced option and then choose the frequency band. Step 4: Now, choose 5GHz. Updated on June 19, 2021. 802.11n is an IEEE (Institute of Electrical and Electronics Engineers) industry standard for local Wi-Fi network communications, ratified in 2009. It replaced older 802.11a, 802.11b, and 802.11g Wi-Fi technologies but was superseded by the 802.11ac in 2013 and 802.11ax (Wi-Fi 6) in 2019. 802.11ay (Wi-Fi 7) is up next. Hi, as mentioned 2.4 or 5GHz is only for WIFI connections. 2.4ghz will generally get you a further away connection, with less speed and the 5ghz will give you more speed but less distance. If you connect via ethernet, you are connected to your router and the same networks as the 2.4 or 5ghz WIFI SSIDs. Many thanks, Tom. 10) Try plugging in by ethernet cable to the router to compare, then plug the ethernet cable into the modem (if separate) to see if this might be an issue with the router. 11) Try powering off modem, router and PC and then restarting in that order with 1 minute in between each. The general solution on Windows is to run the following in Command Prompt: netsh wlan show drivers. Look for Radio types supported in the output. If you see 802.11a in the list, 5 GHz networks are supported. Otherwise, as in this example, only 2.4 GHz networks are supported: Client Wi-Fi radios that support only 802.11g can only connect on 2.4GHz. 802.11a, which so far has not been widely used, runs on 5GHz. 802.11n, which has much higher data rates, can run on either Only a handful of our printers support 5 GHz (802.11 a or ac) wifi. While 5 GHz wifi is faster, it has a shorter range than 2.4 GHz (802.11b/g/n) wireless communication. Originally, the 5 GHz channels were used by routers as a carrier signal to cross-communicate with themselves, while 2.4 GHz was used to connect devices to those routers and the 5 GHz WiFi has a shorter range and the signal strength drops (more than 2.4 GHz WiFi) when going through solid objects, something which I’ll come back to later. Having said all this, I think that devices which support 5 GHz WiFi can still be worth buying for one simple reason: it’s more reliable. w0lrm.
