Getting "Could not estimate first hop speed" line qual It only started happening the last few days, after my entire ISP (century link ) went down in my area. I don't notice anything strange about my tests and I'm not having any issues with my net connectivity other then some slowdown in the evenings related to bandwidth exhaust issues. but I figured I'd check.
However, just in case this is related when I test my speed on speedtest.net the upload always comes out blank if I take multiple tests back to back, even though the test finished. Notice how the share results are different because they show the last test, although I doubt this is related, just wanted to share it just in case.
