WIFI problem - 5GHz on macbook pro

I have got a new macbook pro 2017 (13’’, High Sierra). This is my first mac.

Recently I'm struggling with the wifi connection between the mac and my router. My router works on both 2.4 and 5GHz. I have 7 devices connected to the router and they work without any problems. Some of them are connected to the 2.4 network and some to the 5GHz.

When I connect my mac to the 5GHz network sometimes it disconnects itself (for example during watching a movie or browsing webpages). It seems to be connected (the wifi icon is black) but there is no internet. After a while it works again without touching anything. I tried to change the router channels but it didn't help. I dont't have any problems when the mac is connected to 2.4 GHz network.

hi,

I have changed several settings on my router and MBP. The connection is stable now.

1. WPA2 only - in the router settings..

2. I removed saved networks on MBP and registered again.

3. I set access to the connection for all applications in the bunch of keys settings.

I'm not sure which change was important but it works;)

5GHz is potentially faster but also more susceptible to distance drop-off and interference. The MBA's metal case is an advantage in many ways but a hinderance in others and I've found that my plastic PC notebook can be further away from my router on 5GHz than our MBA or MBP. If you have a router with moveable antennas you may find it useful to try changing their orientation or moving the router. You might also look for sources of interference. Note: if you hold option while clicking on the WiFi icon you'll be able to see signal strength etc which is helpful as you try to work thru this.
