@suisse Actually I realised the issue is with my mobile phone - I've noticed in WiFi Doctor it briefly loses the wifi network. Unfortunately the problem started the same time as I moved home so I thought it must have been the new ISP. Sorry for the confusion and thanks for helping!
@suisse thanks for your reply. I ran few hundred pings against the DNS servers and the ping times look good - solid 10-15ms 99% of the time, max spike 25ms. This proves that the ping spikes I can see when pinging remote servers in Zurich (i live in Roveredo (GR) ) are not responsible for my disconnections. Also at my work place (also in Roveredo) I can see similar ping spikes but I don't get any disconnections on my mobile using wifi there (also from Swisscom). Before I moved home few weeks ago my connection in games was stable, however I was using UPC Cablecomm there. Even on my not very good mobile internet, the connection is stable - no disconnections in apps/games. I think the problem may be with my router (internet-box2), even though the wifi network is always on and with very good strength. This is what I can see on the Diagnostics page in the router admin - it looks like there is a very high ratio (20%) of failed transmitted packets: WLAN 2.4 GHz WLAN name (SSID): vlf-38756 channel: 1 Device Name kwiatek-PC-1 RSSI -40 dBm Latest Tx rate 72222 RxPacketCount/s 85 TxPacketCount/s 156 Pkt_TXFailure/s 32 Current Bandwidth (Mbit/s) 1.7 Rssi per antenna: Ant0: -33 Ant1: -34 Ant2: -40 Packet Queue: 55,55,0,-,-,0,0,0,0,200,0.00,-,-,- 0,0,0,-,-,0,0,0,0,200,0.00,-,-,- Connection counter since last reboot (4 Days 6 h 36 min): Successful connections: 322 Failed connection attempts: 1 Connection attempts with authentication error: 0 Other information chanspec: 4097 tx: 5 inbss: 1 obss: 0 nocat: 1 nopkt: 2 doze: 0 txop: 93 goodtx: 1 badtx: 1 glitch: 328 badplcp: 2 knoise: 92 idle: 98 timestamp: 369517785 Interference Status: Mode = 47.

I am a new customer and I have a problem with the internet connection. The speed is ok but very often I get ping going up to 200-400ms (both over wifi and over ethernet cable). Usually it happens around once a minute but one evening it was as bad as every few seconds! It's bad enough to lose the server connection in some apps/games. My setup:
- internet-box 2
- tv box (disconnected when I was doing the ping tests)
- package: 40Mb/sec
