The Toshiba RealTek LAN Driver installed on my computer is Version: 10.1.505.2015 (Posted Date: ) which I downloaded from Toshiba drivers support site. And I am the only person using this laptop.Īnyway, JohnC_21 fast Startup was already disabled. I came home last night and ethernet is working again even as I am typing it's working fine without me having taken any step to troubleshoot yet. When I started the thread yesterday morning I had no internet connection on my ethernet port, and I used a neighbor's open xfinity wi-fi to access internet. Thank you svim for paying attention, no router just a modem. Note that the at OP did mention there's no router involved. I got the new one with a 2 year warranty. My other router was only a year and a half old but apparently died. I bought a new router and everything has been fine since. I tried all the steps listed plus others on the internet. I can get wi-fi to work on same laptop (open xfinity wi-fi from neighbor). The IP configuration is set to obtain an address automatically. There is no yellow exclamation point in the device manager. Then the intermittent no connectivity issue came back. Then I updated windows 10 to build 1809 and internet started working again for a week with no issue at all. When it first started I had windows 10 pro original version on my laptop, I updated windows 10 to build 1803 but it didn't help. I have replaced the Ethernet cable, but there is no improvement. I have talked to Comcast reps over the phone many times and they tell me it looks good on their end and that they can see my modem, they did a reset of my modem but it didn't help.Ĭomcast has sent 2 different techs at my place and they both said the wiring has no issue. The issue comes and goes, meaning sometimes there is no internet in the morning, I will come home from work at night and internet will be working.

Without any updates or changes to my system. All of the sudden about a month ago, I started getting no internet connection intermittently


I have had the same setup for at least 2 years without this problem. Toshiba satellite laptop S75 hardwire to a personal modem arris sb6141, my ISP is Comcast xfinity. Running network troubleshooter gives me the error message: "Ethernet" doesn't have a valid IP configuration Problem: intermittent no internet connectivity
