" rel="nofollow - Hi, I've recently built a new computer (Win7-64) and everything was fine, had internet connection etc. I came back yesterday morning & internet connection was suddenly gone? Modem/router had disconnected itself, so I reconnected and now I have internet wi-fi ok but still no broadband on my desktop PC? Diagnostics suggests there is no link to the network adapter, ie the ethernet cable is faulty? So I tried another cable and still the same problem? I'm pretty sure the motherboard's ethernet port is fine (mobo is brand new). It doesn't light up, but when I run the LAC "Identify Adaptor" diagnostic it starts blinking, so I assume it is ok? Would a faulty cable cause the port not to light up? It could be that both my ethernet cables are faulty perhaps? Should I buy a 3rd one & try it? Also in Device Manager nothing is highlighted, the network adapter & drivers are installed ok etc. What should I do? I'm tearing my hair out with this! It's a brand new build & was performing excellently until yesterday!? Thanks in advance -- :) |

" rel="nofollow - OK so I managed to get a 3rd ethernet cable (brand new!) and still no go. I hooked up a laptop and no connection there either. So... it is the modem ethernet ports? It has 4 ports, I've tried them all. Sheesh... so frustrating! |

" rel="nofollow - I would try connecting the system to another device other than the modem/router to rule them out as the issue. By the sound of it though, I would guess the fuse on the LAN port has blown (power surge through the LAN cable). This kind of thing is usually caused by lightening somewhere along your cable line, have there been any storms in your area lately? -------------

" rel="nofollow - Thanks Xaltar, but could it be the fuse if it still blinks when I go LAC/Properties "Configure"/Link Speed/Identify Adaptor? There's been no storms here btw. I have yet to try another modem. I'm ready to give up & start a fresh new Win7 install. PITA after spending days installing tweaking all my apps & settings & stuff. Gah! |

Don't do a fresh install. Sounds like your modem went belly up. Test with another to verify. |

I'm with Wardog here. Either the modem died or the LAN port did, either way software won't help. The fuse does not effect the LEDs. The fuse is in line with the cable and designed to stop power surges reaching more sensitive components. A blown fuse means the cable is unable to transmit signals, the LAN controller itself is still working even with blown fuses so indicator LEDs and diagnostics would still pass. Hopefully that isn't the case as there is little that can be done about it. The fuses are not replaceable, at least not without the skills of an electronics expert and a pro soldering rig. Try another modem first (that is the more likely culprit) then get back to us. -------------

" rel="nofollow - OK will do, I'm borrowing a friend's modem tomorrow. I appreciate your responses, you guys. I'll post back my results. I'm hoping it's the modem? Because the motherboard is brand new! Anyway I suppose I could just add a PCI network card if it's the motherboard's LAN port, right? Anyway try a different modem first... Thanks again! :) |

" rel="nofollow - One qu', if I may... If it IS the modem, shouldn't the motherboard end of the ethernet cable still light up when it is plugged in? Or does it need both ends connecting properly? (Sorry for noob question)... |

The LEDs are Activity LED and Connection LED, both require a signal so no, if the modem's LAN port is toast there wouldn't be any LEDs lighting up. Connecting the patch lead (LAN cable) from your PC to say a laptop should give you a Connection LED. It won't allow data transfer but it is useful to see if the port is dead. -------------

" rel="nofollow - What do you see in the Device Manager entry for the Intel I218V networking chip? If you have the Intel networking driver installed, there are diagnostic tests that can be run. What does the Windows Network and Sharing Center say about that Internet connection? You can run the Troubleshooter and see what the result is. ------------- http://valid.x86.fr/48rujh" rel="nofollow">

" rel="nofollow - Hi Parsec, I'm still waiting to try out a new modem bit later today... The Intel I218V ethernet connection is listed in Device manager and "device is working properly". When I go to Properties/Link Speed, the "Identify Adapter" diagnostic starts the motherboard's LAN port blinking fine (as I mentioned before). When I run the Diagnostics/Connection test, I get: "This adapter does not have link. Make sure the cable is connected & the speed & duplex settings are configured correctly on the adapter & link partner." When I run the Diagnostics/Cable test, I get: "This adapter has no link... poor quality cable, bad connection" etc [NB: this is the 3rd cable I've tried & it is brand new; it's not the cable) When I run the Diagnostics/Hardwire test, it all checks out ok. "Register Test", "EEPROM Test", "FIFO Test" & "Loopback Test(s)" all pass. In Network & Sharing Centre, when I try to connect I get Error 651. The troubleshooter says it's the cable - "A network cable is not properly plugged in or may be broken". But like I said, this is the 3rd cable I've tried & it is brand new. Any ideas? I am trying out another modem this afternoon. I will report back. I appreciate the help here, thanks! :) |

I would say your results indicate no Broadband Internet signal coming from your router/modem, plain and simple. You said you tried all the Ethernet ports on the router, so it seems the Broadband connection died in the router. The WiFi was still working, meaning you are still getting a signal from your ISP. That makes you thing the router is Ok, but the Broadband switching circuits seem to have failed. Electronic components fail without warning, even with no power surge or lightning strike. It's possible you slept through a storm, right? I had a storm at night last week, I'm the only one in the house that heard it. Had a nearby lightning strike, scared me like crazy! The next day, all the HDMI inputs on a flat screen TV no longer worked. The TV was connected to a surge suppressor, and otherwise still works. The cable box and DVD player worked fine, connected to the same surge suppressor. An HDMI switching box I use with my monitors and PCs also stopped working. It and the PCs were connected to three surge suppressors in series. All the HDMI outputs on the video cards or integrated graphics work fine, as well as the monitors. A new HDMI switch box worked fine. I also lost a simple network switch used for the basement. No signal out of the switch at all. But connect the network input cable to the switch directly to a PC or XBox, and it worked fine. As I like to say, stuff happens. The results of that stuff may not make sense, but when I see it myself, why continue to ask why? ------------- http://valid.x86.fr/48rujh" rel="nofollow">

" rel="nofollow - Wow Parsec, I think I'd give up & throw all my technology into the bonfire if everything clunked it like that all at once! Lol! Technology can be a double-edged sword, that's for sure. OK, so anyway I'm cranking again! I installed the new borrowed modem, went through all the ISP set-up stuff, and got connected! Yay! My computer (brand new build) is up 'n' running like it SHOULD be again!! OK get this, this new modem was a temporary lend, so I had to give it back, so I put my flunky modem back, and went through the same set-up procedure. And it works now? So, although I am ecstatic, I am left confused & wondering just what the hell went wrong. A simple modem setting was wrong? I was very careful with that stuff before... I must have neglected something? But what? Oh well. I'm sorry if I wasted you people's time. I very much appreciate your help & support! If it wasn't for your advice & support here, I would have been reformatting my hard drive by now, and losing everything. So thank you!! Fantastic tech support here! :))) |

Ha, the number of times I have seen that happen  In all likelihood the modem properly reset while disconnected. -------------

Or a: the borrowed modem isn't compatible, b: the incorrect firmware loaded for the OPs ISP, c: The modem wasn't provisioned at/for his location. A call to the ISP could have confirmed many things towards the OP's final issue with the borrowed modem. |

The borrowed modem worked, he then had to return it and tried to install the original modem again and then that too worked. So yeah, probably a hard locked modem that needed to be powered off long enough to fully discharge. Possibly an interrupted automatic firmware update? Either way he is up and running again now  -------------

OMG, after all your high tech diagnosis and testing, we forgot the most basic thing to do when a network connection fails... Power cycle the router!  That's the first thing I do when the home network is not working, and 99.9% of the time, that is all it takes. Then I'm the hero and I really did a lot of nothing. I'm guessing you never did that? An innocent mistake, too easy, why would it make a difference? Uhm, ever hear of a reboot?  Why does that make a difference? Something gets corrupted, and asking why takes us into that endless tunnel of questions that we will never answer.I bet you didn't need to reconfigure one thing in your router again, did you? Only if you lost your settings when you put the original router back again, which normally should not happen. I would bet you did not need to even do the setup procedure, but that doesn't hurt. You would of tossed it into a bonfire?! Yes I know the feeling, but when I get started chasing a fix, I can't stop. When the simple things fail, I know I have a real problem. All I did was use different inputs and outputs for the TV. The good news is this might inspire the need for a 4K TV!  ------------- http://valid.x86.fr/48rujh" rel="nofollow">

" rel="nofollow - Lol! No everything is working now, thanks again. Yes my ISP was the first port-of-call, they walked me through the modem's "Quick Start" thing but obviously neglected some settings! I had of course rebooted the modem many times before this, btw! I am blaming my ISP for incompetent tech support!! I'm still not sure what the problem was, but when I went through the modem settings myself, I tweaked a few things & anyway now it works & no problems. I still dunno what the problem was tho'? Except a setting was missed by the ISP, but I inadvertantly plugged in the right settings when I tried the borrowed modem? Then "somehow" repeated" the same thing when I re-connected my modem? Sheesh, who knows. It's all working now, and thanks you guys, now I'm gonna throw myself into the bonfire. |

I'm not a rich person, but I recently bought a 48" 4K LED TV (Bauhn) from my local Aldi ha ha... It was a big risk, I know (was expecting to return it)! I couldn't be more happier with the picture quality! Superb! Was half the price of anything else on the market. |
