Trouble with one guy’s Macbook at his worksite. His wireless connection works fine at home.
Opened a browser and terminal. Ping the router at 192.168.0.1 and it pings (but too slow = like 4-5ms at best)
Try to open a website,
the ping to the router stops. Times out maybe 10-12 times. Then starts 10-12 times. Sometimes the site loads, sometimes not.
nslookup website from terminal - checks out. Ping website from terminal, works fine. Open browser, lose ping, lose nslookup.
Only THAT Macbook, others work fine. Auto DHCP… static makes no difference. Added Google 18.104.22.168 to DNS, no difference
Any ideas where or what to look for?
