I am facing an odd issue on macOS High Sierra 10.13.6. My wifi connection within the office is really messy now. Before I didn't have any issue for a few months. Furthermore wifi works perfectly fine with other networks.
There are 3 things happening periodically.
1) I am losing internet connection, but the laptop is still connected to wifi.
I was pinging 192.168.1.1 and everything seems to be fine, and then all of the sudden I start getting timeouts:
64 bytes from 192.168.1.1: icmp_seq=14195 ttl=64 time=4.036 ms 64 bytes from 192.168.1.1: icmp_seq=14196 ttl=64 time=4.597 ms 64 bytes from 192.168.1.1: icmp_seq=14197 ttl=64 time=3.270 ms Request timeout for icmp_seq 14199 Request timeout for icmp_seq 14200 Request timeout for icmp_seq 14201 Request timeout for icmp_seq 14202 Request timeout for icmp_seq 14203 Request timeout for icmp_seq 14204 Request timeout for icmp_seq 14205 Request timeout for icmp_seq 14206 ping: sendto: No route to host Request timeout for icmp_seq 14207 ping: sendto: No route to host Request timeout for icmp_seq 14208 ping: sendto: No route to host Request timeout for icmp_seq 14209
Tracerout is timing out.
2) Laptop is disconnecting from network and reconnecting in few seconds
3) Laptop seems to be connected (but now internet available), however when I click on wifi icon, I can see only 1 network (the one I am using) and no other network. After turning it off and on I can see 5-7 different networks
What I've tried so far:
- Remove network and connect again
- Remove and Re-Add The WiFi Service
- Tried to use static IP
- Reset PRAM and SMC
- Add new location in Network settings
- Reinstall OS
- Restore factory settings on a router
- Delete The Internet Preference Files (com.apple.internetconfig.plist, com.apple.internetconfigpriv.plist and others)
Unfortunately, the issue still persists. I am running out of ideas... I thought that the adapter could get broken but it works fine with other networks. On the other hand, I am the only one in the office facing this issue along with router so doesn't seem like router issue either.
Any ideas how to troubleshoot it?
