    Epox 8rda6+ pro no more ethernet

    Hello.
    Third post here XD (Ok, I'll stop counting :P)

    Ok, I have this Epox motherboard that I had given to a friend for let him use until he got a new laptop.
    But after he gave me back my motherboard, I tried it and I found that the integrated ethernet card don't work anymore. It seems that a lightning hit the phone cable (unluckily we have most of the last mile cable on poles ) and the ADSL router, broking only the power supply of this one, but my friend claims that at that time the computer wasn't plugged to the router, so in any case I can't know what was the cause of this problem.

    On the BIOS settings I still can decide (obviously) either to switch it on or off, and even set a mac address if I enable the feature, but if I, like, try the network boot the motherboards shows me a message that no device is plugged (naturally with the bios setting to "auto", the only choice available except "disable"). So to say, not only windows doesn't view anymore the integrated device but even the BIOS.
    I suspect that the problem can lay on the power line to the card (i.e. a fuse) since the leds are off, but I'm not so sure and it's just an idea.
    In any case, this is the situation and I want (and need) to fix it since I need it for helping another friend, and we don't have any spare pci ethernet card (nor we have any money to buy one, naturally).

    TIA again for any help provided

    Disable network boot in the BIOS. Before claiming the ethernet port is bad.

      The network boot is ALWAYS off, I said that I tried it but it meant that it was ONCE.
      And, btw, if the network boot says to me that there isn't any device, what do you think?
      And what does it matter, btw?

        Hey, I hope you didn't get offended and are not answering on purpose due to this...

          Nope, not offended.

          There's that message about telling you to check the connection if you don't disable LAN boot, which is stubbornly enabled by default on some board BIOSes!

            I see, thank you.
            In any case lan boot is normally off. I tried switching it on on the bios and alternatively hitting f11 (if i recall correctly) for choosing boot device: both showed me a message that there wasn't any network boot device, while normally, as far as i can remember, when those options are choosed they show me a different message, with technical data running and such things.
            I hoped to find someone that knew this motherboard or at least where and what to check, with, like, a multimeter or something else.

              Post a picture of the area near the ethernet port. Looks like that Cicada chip does the ethernet handling. Not sure though.

                Yes it is that chip, even though mine is called Vitesse.
                Here are the pics I could take:

                  Re: Epox 8rda6+ pro no more ethernet

                  I guess the first step would be to check if all of the proper voltages are coming to this chip. To do that, you will need the VSC8201 data sheet.
                  They have it on their website, but you have to register. This is the link to all of the related files for this chip:
                  https://www.vitesse.com/products/pro...number=VSC8201
                  If you don't want to register, you can open the link/item labeled "VSC8201 / RTL8201BL Dual PCB Layout Applications Note", download the ZIP file, and open the "Dual_Layout_AN_11.pdf" file. Page 4 shows where some of the voltages go.
                  This chip uses:
                  1.5V for VDDPLL15 and VDDREC15
                  3.3V for VDDPLL33, VDDREC33, V+A33, and VCC_MAIN33
                  See if you get those voltages. U5 looks like either a 1.5V or 3.3V regulator. Check what voltage it is outputting and if it stable.

                    Home network connection problem
                    by davg
                    I just bought a new ThinkPad laptop and I need to connect it to my home network. I have several computers on my network and can see each other in File Explorer and the older ones can communicate with each other (even with the new one) but the ThinkPad can see the other computers but can't communicate with them. I get the (network error 0x80070035 The network path not found). I tried several scenarios that I found on line but none of them worked?? Since the other computers on the network can communicate fine I'm assuming the problem is with the setup of the ThinkPad? All computers are running Windows...

                    Maximum speed should be marked on network ports
                    by japlytic
                    I noted that a number of consumer entertainment devices have the maximum speed marked on the wired network port and considering that there are broadband plans faster than 100 Mbit, the wired network port can be a bottleneck since some routers do not have Gigabit (only 100 Mbit) support for the WAN port let alone the wired network ports.

                    One other thing: Certain low cost network cables only have two pairs which limits speed to 100 Mbit.​

                    iMac A1418 - No LED, no power after overvoltage on Ethernet port
                    by ryogadan78
                    Hi guys, I need your help again.
                    I have this iMac from a customer that shut down during a storm along with all the other devices in the house. In particular, the router, connected via Ethernet to the iMac, caught fire.
                    When I removed the screen from the iMac to check the status of the LEDs, I noticed that none of them were lit. I had a perfectly compatible and working power supply, so I tried it right away, but the problem remained the same (no LEDs). With the thermal camera, I noticed only a slight warming (32 degrees) of the NCP1605BG chip on the power supply. The rest was completely...
