Windows 10: Intermittent "Not connected to a network" errors while browsing

    Intermittent "Not connected to a network" errors while browsing


    Hi, new here and have a new windows 10 (factory installed) PC HP desktop computer with Comcast Wifi internet modem and wired Ethernet connection.

    I don't know much about computers, but I'm having a constant problem that I can't seem to solve. No computer experts close to me to help out, so I hope someone here has some simple advice for me.

    While I'm browsing the web, I'm frequently getting a "not connected to an network" error page. If I wait a few seconds, the webpage resumes. If I'm in the middle of an action when this happens, it's lost and has to be redone. When I just clicked here on 'preview post', I got that error page.

    When I look under my computer settings, I can see it say "Ethernet connected", then seconds later "Ethernet not connected.

    My net adapter is Realtec PCIe FE Family Controller. I have disabled the Wifi adapter that was enabled by default, as I'm not using Wifi for anything.

    Followed by the 'not connected to a network' error page, I often get the 'page cannot be displayed' error page. I'm using the free Norton Security Suite that came with my Comcast/Xfinity IP account, and IE11 or Edge browser.....same problems on both.

    I hesitate to make any big changes on my computer, as I share it with my husband, and like I say, there's nobody close to us to help out if we get in a bind. I've done full system scans and have the latest updates.

    My Ethernet cable was working fine, but I bought a new one a few days ago just to make sure, it's not the cable. On one screen on my computer settings, it was saying that my network cable was not connected. It is definitely connected.

    Is anyone familiar with this problem with a Windows 10 computer? Didn't have such an issue on my older Windows 7 Lenovo computer. Any advice is appreciated.

    You are loosing your ethernet connection intermittently. This can be any number of problems. What are you connected to for internet accesss? Router, modem, ? Is the connection from the source signal to the access point good? Contacting Comcast would be a good idea and explain the situation to them. If that fails to resolve the issue contact your PC manufacturer for further assistance.

    I have an Xfinity Wifi modem, that I think has a built in router. How would I check the connection from the source signal to the access point? Not very knowledgeable about computers here. Thanks for your advice.

    When it happens does the internet light show its connected on the router if it goes out its router connection fault if it's on does the light show the PC port connected if it goes out its a PC or cable fault

    Xfinity modems usually have a series of lights on them. In most cases they are marked but you have to look closely. Locate the one that says Online. That light should always stay illuminated and steady not blinking. If that light blinks on occasion or goes out and then comes back on then that would indicate a signal loss. If you do not witness that but your connection still drops then you have some other issue.

    My next suspect would be a NIC driver issue.

    Just an update. I looked around online for a simple solution and I found it, I no longer have the problem. I went to my power settings that were automatic power saver by default. I then changed it to 100 Mbps. full duplex, that didn't help, but I left it there, not interested in saving power if the computer wasn't functioning properly.

    Saw a tip from a gamer in a video, and changed that setting again to 10 Mbps. full duplex. I'm not sure why, but since I did this I haven't been disconnecting all the time while browsing the internet, no Ethernet cable disconnected errors anymore. I'm very happy that's behind me. Thanks again to everyone here for your input and advice.
