laptop can receive 5 g signal, it is necessary to meet two conditions, routers and wireless network card need to support 5 g.
1. From here we can see, only support 802.11 n and 802.11 ac protocol router can launch 5 G signal (802.11 a has eliminated), at the same time need two routers support 2.4 G and 5 G spectrum can be realized, currently on the market a lot of 802.11 n router does not support dual-band, mobile phones and laptops are search less than 5 G signal, can only use 2.4 G signal, while support 802.11 ac router can be received 2.4 G and 5 G signal at the same time.
2. Need laptop wireless card support dual-band and support 802.11 n or 802.11 ac, these two protocols can only receive 5 G spectrum signal, lenovo models support 802.11 BGN wireless network card are single frequency, only support 2.4 G, unable to search to 5 G signal, only support 802.11 ac signal of the wireless network card can search to 5 G, lenovo computer delivery only Intel's 3160, 7260, Intel, Intel 7265 this 3 models of wireless network card support ac 802.11 protocol.
3. If in accordance with the above two cases, laptop or just search to a signal, usually because of the router in the 2.4 G and 5 G signal network name repeated, the following figure, only need 5 G network name of the router manually modified into the name of the other, you can search to two wireless signals, one is 2.4 G wireless signal, a wireless signal is 5 G.
