And 9 - 15 - 25 pin adapters, male and female. And gender benders. Mine have been in a box for a long while now.

I have a sat dish installers set up box. Battery powered, LCD screen etc. Shows channels, signal strength and lots of other nearly useful things. It needed an update, and all it has is a 9 way D connector. No current computer with RS232 now, so I had to dig out my USB - serial dongle, and a suitable cable. Worked OK. Bits now back to sleep in the cables box.

Windows 10 is good at providing a driver for most 'extras' you fit, certainly enough to get you up and running. What does the windows network trouble shooter say when you open it up. If its a driver issue more often than not it will tell you.
 
i have one like this.USB 3.0 dongle soon as i plug it in win 10 finds it and loads the drivers...simples

Long shot but have you tried a different ethernet cable? I've recently been caught out by a faulty cable (see post #86) and ethernet cables do have a habit of losing connections in the plug.

Very good point. I have had cables faulty from new, and also some drop connection after a good period of working fine. I try to wire as much as possible in preference to WiFi, and in a few cases had to make up my own cables. I invested in an ethernet cable tester in one of A*****n cheap offers. That has 2 parts, that can be separated to go on each end of a long run, and cycles through each wire showing good or bad on LEDs. Maybe over the top normally, but only cost about the same as 2 medium length replacement cables at the time. I am retired now, but the time saved using it at my 'working' rates would make the cost a no brainer.

We need get this sorted for our own serenity. Can you share your PC model and what you are trying to connect ? You have the best brains on the forum at your disposal all sat on the edge of our keyboards. :cool:
Andrew.
 
Hi Smudger,
When you connect an ethernet cable do you see the icon under the arrow in the pic below ?

If you do, then Windows thinks you are connected (it can see the cable connection to the router) but the ip settings need to be altered because they are not correct.
If you don't see the icon then other things need to be done ... :)

Yes i did see that icon. I disabled the ethernet & then enabled it. Still no good.

The icon shows that the computer is connected to the internet but appears to have problems with ip settings with ethernet while the ip settings are ok with wifi. This needs actions in the Terminal (Admin) window. with commands similar to 'ipconfig flushdns' etc. I had similar problems some years ago on an old computer and it took time to get it right. Have a read through the following websites

Thanks oM, i think i`ll buy a better ethernet cable. The ones i`ve tried are cat5 & cat 5e.

Your Windows seems happy with the cable because it shows the connection icon. Ip settings can be quite tricky to set up as I remember. On one computer I had to use Google's DNS 8.8.8.8 instead of those provided by my internet provider. As a last resort you could reinstall Windows ...
 
Try renewing the IP settings:-
Right click on the Start icon and select Windows Power Shell
After the prompt type ipconfig /renew (make sure there is a space before the /)
Press enter and wait for a confirmation message then try again.

Also have you tried different ethernet sockets on the router?
 
Hi Smudger, What are you connecting to, is it your modem/router and from there to the internet, or are you connecting 2 computers together ? As soon as you connect anything to anything else, you have a network. As mentioned above, networks rely on IP address to sort out who is talking to whom. In a network, there can only be one thing that hands out IP adresses, everything else has to accept what it is given. If you are connecting to a modem/router, then that will be 'in charge' of IP. How or why is not really important here. Your computer should be aware of this, and play ball. It is fine when it is using WiFi, but there may be some setting for ethernet that tells the computer to be in charge of IP, and then there will be arguments and sulking. Your cables at cat5 or 5e are fine, unless they are faulty, and I suspect they are OK from your previous comments. You aren't trying to connect with 100m + of cable are you ?

Yes. Definitely the way to go. Make sure WiFi is disabled on the computer, there may be a preference if it is enabled that ignores ethernet.

I have just tried that & it says " no operation can be carried out while media is disconnected" It is connected & enabled.
 
I know this is a silly question, but your router does have Ethernet turned on ? My router has 4 Ethernet sockets, and they can be individually enabled or disabled by logging on to a config ‘web page’ built into the router. Using Wi-Fi, and the instructions for the router, have a look. Usually by entering 192.168.1.1 or similar into your browser.

You will need a ferry ticket and a brick for my windows :).

Odd one is this! I'm just wondering if the problem is with the ethernet card in the PC. If you're OK diving into the innards of the PC try removing the card, wipe the connections with a soft lint-free cloth and replace, first taking the usual precautions i.e. switch off pc, disconnect from the mains and press the PCs 'on' button to discharge any charge and touch a radiator to discharge any static (apologies if I'm teaching my grandmother to suck eggs!).
 
it is straing.. after reloading win on my other pc this afternoon to try it the lan works ok....and the wifi does...... as you say the lan device might be capoot. best of luck...

Tried an experiment ... :)
I was running my laptop using wifi and opened the Windows Terminal (Admin). I do this with a right click on the Start icon and typed in ipconfig /all (note the space before the forward slash is important) All the details of the Wireless Lan adapter Wi-Fi appeared

Without shutting it down I then carried the laptop over to the router and connected with an ethernet cable. After a short pause the laptop automatically switched over to Ethernet because I have it enabled as well as wi-fi.

I opened the Windows Terminal (Admin) and typed in ipconfig /all
All the details of the Ethernet Lan adapter appeared

I would be interested to know what Smudger's laptop actually shows when the ethernet cable is plugged in, the wi-fi disabled and ipconfig /all is typed in the Windows Terminal (Admin)

I'm running Win11 but for the above it is not much different to Win10

ps. All old computers used Ethernet before Wi-fi became generally available
