Hello,
I returned to Windows 8.1 after 3 painful weeks with W10, and I hadn't found my usual wifi, so I was using my Ethernet cable. Everything was fine until I unplugged it this morning to go out with my laptop, and when I got back, I plugged it back in: no internet (Freebox), no signal...
I disconnected all the cables, restarted the Freebox, the time is displayed, everything seems fine, but there's no internet signal, the diagnosis says no network detected, and the automatic repair doesn't lead to anything.
I eventually got internet with FreeWifi, which is not in my name and requires an ID and a password, which I have. It works ("connection successful").
First, I'd like to know how to get back online with my Ethernet cable.
If you have any ideas, thank you. :-)

Re,
With the Ethernet connection, you don't need a network key or anything else, it's not like Wi-Fi, that's why I advised you to look into the cable topic.
That said, you ask for "ideas from others"… there are hundreds of possibilities, don't think I gave you the only one that was on my mind, I only gave you the easiest one for you.
Wi-Fi is not linked to Ethernet, it always requires a key… which is usually written on the label of the BOX… but it might also have been changed since… So only the one that's readable inside the FreeBox is valid… And you need to be able to connect to it.
The administrator may have also banned your MAC address from connecting, so you will be banned no matter what the mode of connection… We'll see..??
Your Wi-Fi could very well be connected… to a BOX without you being connected to the web (internet)… if the gateway or DNS is not properly configured..
FreeWiFi is something else, it's an Open HotSpot, so no Wi-Fi key, just a name and password on the first Web page… But the speed remains limited… but it proves that your Wi-Fi works.
You might have specific problems if you are at a vacation site, rentals, hotel… that have placed controls on their networks.

Thank you Jeannets, indeed I must have changed the key since the connection was established with the key I created when I installed my box.
Unfortunately, this does not allow me to access the internet any further, despite a wifi connection being indicated as established.
I am at home, with just one laptop, I only unplugged my ethernet cable to take my computer out for an hour to show some photos to a neighbor at the end of the building. When I came back, I reconnected it and no longer had access to the internet, neither via the cable, nor with a new cable, nor with my wifi which is still indicated as "connected" after entering my key.
I don't see why an administrator would have "banned" me just for unplugging my cable and taking my laptop out for an hour to show nature outing photos to a family friend? Can we know if we've been "banned"? (It's a strange thing, but hey, might as well check).
Otherwise, regarding the gateway and DNS, how can I be sure?
(Does simply unplugging the ethernet cable disrupt anything in these gateway and DNS issues?)

You should turn off your PC... then your BOX, for five minutes..
Then turn the Box back on and then the PC..
If you're banned, it's in your house, in your BOX, someone who lives with you.. I don't know your situation...? I'm just imagining possibilities, that's all.
The DNS is configured in your Windows, control panel.. Network, TCP/IP properties... there are DNS1 and DNS2
I suggest you set DNS1=208.67.222.222 and DNS2=208.67.220.220
Then turn the Box back on and then the PC..

Thank you Jeannets for your last response. The next day, determined to test what you suggested, I was surprised to discover that my Wi-Fi was there, as if it had come back on its own without me entering the key when I turned on the computer, so I no longer had to connect via the Free Hotspot.
This has happened to me before where I was without Wi-Fi for a day or two without understanding and it came back on its own, but this time it lasted a bit longer. Why was it stuck like that for several days? It's a mystery. In any case, I have my Wi-Fi back. Thank you for the follow-up. :-)

Hello,
I suppose that the wifi from the BOX doesn't stop... but it's your PC that can't connect to it...
--- In fact, you need to make a clear distinction between connecting to the Web and connecting to the wifi... You can very well be connected to your BOX's wifi without being connected to the WEB... yes indeed...??? And the search is not the same..
-- Especially if you are on a dynamic IP and there are several people connected in the house..
-- There can also be radio interference on the wavelengths... especially with "N" wifi in "populated" areas
- To avoid these problems, I recommend removing "N" wifi from the BOX and changing the wifi Channel... This way, you will operate on standard wifi, B or G but not N, and very few people are able to tell the difference in common usage.

Thank you for this clarification, I am alone at home with only one computer and the problem first occurred after the "automatic" transition (which I always refused and it started by itself one evening) from W8 to W10: 2 days without wifi, then it came back on its own until the day a month later when I went back to W8.1. Wifi disappeared, I used the ethernet cable, then the cable stopped working and apparently I couldn't have my wifi either until it started working again on its own.
I don't understand but I will try to disable the wifi N in the box and change the channel. Thanks. ;-)

re,
Even if you don't have internet... the BOX radiates its wifi, it transmits nothing, but the broadcast exists... so the wifi must exist.
-- Your transition to Win 10 has certainly changed some things... because the drivers that work with one do not necessarily work with the other.
-- You may also experience internet outages, especially if you are far from the local exchange... and FREE is also well known for its inconsistent speeds...

Good evening,
try with another cable.
Check if the tab is not broken..??

Does anyone have another suggestion?
Could it be related: when trying to connect to my wifi (Free), it asks for my security key, but it’s declared "incorrect." (?)
I entered the 18-character code including 1 letter found on the box label, being careful.
And yet, I manage to connect via someone else's Freewifi, with my username and password.
If anyone understands the problem, thanks for your suggestions. :-)
So I'm going to close this subject to create another one because the problem is different. Thank you. :-)
It might be the IP address that is misconfigured. I'm not an expert, but I often have this kind of problem because I use several PCs on the same network, and it usually comes from an IP address conflict.
(Moral: my laptop is a homebody, touchy, and vindictive.)
