I’m having problems connecting to a certain website. It’s random whether the site loads but recently it’s been getting worse. What happens is that I turn my router and computer off at night, then after rebooting in the morning more often than not the site in question will not load. This happens even though I could access it the day before without any difficulty. A reboot of the router is what triggers the glitch. All other web sites load as they should.
The site itself is ok since I can access it via a proxy server and DownForEveryoneOrJustMe.com verifies it’s online. I suspect it has to do with my computer since I can access the site using an Android tablet via wifi (same router & modem).
Things I’ve tried on my computer:
- tried 3 different browsers (Firefox, Safari, Opera);
- cleared the browsers' caches and disabled firefox addons
- ran Onyx in automation mode, rebooted.
- deleted SystemConfiguration in /Library/Preferences/SystemConfiguration then rebooted.
- tried booting into 2 different HD disks.
- flushed the DNS cache (from Admin account)
- added/removed DNS addresses on Google & OpenDNS. Currently use my ISP’s DNS addresses.
- disabled OS X firewall briefly. Disabled & reinstalled GUI app for OS X firewall.
- disabled LittleSnitch, rebooted.
- checked /etc/hosts (localhost entries only)
- changed MTU to 1453 in Preferences > Network > Advanced > Hardware (Manual, 1453)
- called my ISP. They told me it was a problem with my computer.
- A ping test results in 100% packet loss and Request Timeout.
Router & modem
- reset router and modem to factory settings and rebooted.
- tried 2 different routers; one wifi, one wired, same maker.
- bypassed the router so that the modem was connected directly to my computer. Problem persisted after modem/computer reboot.
I have no anti-virus software installed but I recently upgraded to a new modem. Am using a Macbook Pro on OS X10.10.5. I’d appreciate any suggestions as I’m out of ideas. Thanks.
