Routers / Switches :: Internet Dies When Connecting Ethernet Cable?
Oct 25, 2012
I've got a Cisco DPC3825 modem that I also use as a wifi router. Conntected to it I have 4 eithernet cables:
1. From PC to Router
2. From another PC to router
3. From TV to router
4. From a Dlink Powerline Adapter to Router.It took me a while to figure this out but when I unplug all the eithernet cables and plug back in #1 and #2 (from above) the internet works. When I plug back in #3 and #4, the internet dies. Meaning, I am connected to the network but not the internet. I've reset the modem, changed SSID and restarted the PC many times but still can't figure out this issue.

Is there a difference in an ethernet cable and an Ethernet networking cable? I have an Ethernet cable and a 6 port splitter I am trying to connect. I have 4 ports in the router that are in use. When I connect them to the splitter nothing s working.

Although I haven't looked through all the forum topics I couldn't find anything very similar to my situation. I have a rather large house and my modem/router (Netgear DGND3300 v2 due to DSL) is in the very corner. Given this most of the opposite corner of my house gets either poor or no connection; however, I do have an ethernet cable run across the house through the basement to my home theatre setup. This is where I encounter another problem, I need multiple devices to be connected via ethernet and I also need to have wireless in that same area. In my mind I picture myself connecting a second router to this ethernet cable through which I could have wired connections to all my devices, and a second router broadcasting wirelessly. I'm familiar with some types of wireless bridging, but I'd rather use more of a wired bridge concept if possible, but I've never really seen something like this. The question is, is this possible? Or, what is another possible way to achieve the same results? The only other thing I can think of is to run an ethernet hub from the original wired connection to my home theatre so I can connect multiple ethernet devices and run a separate wireless extender or something, but this just seems pricy.

Yesterday my main computer lost internet connectivity after avast! ran an antivirus scan and removed several viruses. I spent much of the day yesterday researching the possible problems and did not come up with any solutions.My computer's OS is vista, and the network status says it is, "Connected to identifying". If there is any additional information you will need, I will gladly provide.

I am trying to connect a Netgear wirless router to my cable modem. I have followed the instructions on the set up wizard but it fails to get a connection with the IP and DNS info I provide.I got the IP address info by connecting intially direct from the modem to the PC and then went to Run CMD and type ipconfig /all. I then started the set up wizard and followed the instructions, turning things on in specific order etc. After input the IP and DNS info it reports an error and tells me to check the address information is correct.My internet is a static IP connection (so it tells me and the IP information doesn't change).

my Netgear WPN824v2 router won't connect to the internet. It stopped connecting after a power outage 4 days ago. All local connections work fine. wireless unaffected. I tried a different router, but it wouldn't work either. Contacted my ISP, they said get a new router. Tried re-installing firmware, no change. I haven't tried it on a different internet connection yet, but plan to visit a neighbor and do some begging

After a power failure nothing could connect to the internet anymore. I called MTS (ISP provider) and they had me change some setup on my PC. Now my PC connects to the internet, but nothing else will connect (X Box, WII, iPods, Laptop). They were connected wireless before the power outage through my router. MTS said they are only responsible for ensuring their model works, not routers.I have checked some router settings. It is set for DHCP with 50 users.

I have a home lab. I am trying to connect a 1710 to a 2610 with just using the fast ethernet ports. I understand that serial connections and t1 csu/dsu connections use clocking, etc. How can I configure FA ports to do the same AND be routable?

I need to connect 4 Floor Building with 4 Cisco 2960 - 48 ports switch each other and it needs to be through a fiber. So all PCs connected to each switch would reach the LAN/WAN from the other switch. (attached is the image here with)
I see that the 2960 has 2 SFP ports each port of each switch should connect each other or how?
My simple question is:
1. What cable / patch code I have to use = Single-mode or Multimode? ( distance for each switch will not more then 25 mts)
2. Do I have to use SFP or SFP+ module?
3. What kind of SFP/SFP+ module I have to use = Single-mode or Multimode?
4. What kind of connector should patch code have = LC / SC or ?
5. How to connect each switch with redundancy like ...each switch should be interconnected with each other or I have to choose Cisco 3750G which has more then 2 SFP ports (option#1 & opetion#2 = attached here with) =
Best practice for connecting cisco switches over fiber.

windows update did its thing but as soon as it finished downloading and started installing my AVG anti-virus pop'd up requesting to move some files to "the vault", when that happened windows finished installing and asked my computer to restart, after it restarted i tried to go on AIM and Ventrilo (aka Vent), here's i knew something was wrong, I couldn't sign in to AIM all it said was "waiting for Network..." and Vent just simply said "unknown last ip address" I went to command prompt > ipconfig where it said connection-specific dns suffix it was blank, for ip address it still showed my ip same for subnet mask there was still some numbers but, for default gateway it was blank, thinking it must had something to do with the drivers window installed I did a system restore to two days ago, after it rebooted I thought I fixed it, I was able to sign on AIM as well as Vent even able to use google chrome and watch a friend stream on live on twitch tv, so calling it a night I shut down my PC and when to sleep, now to the title, woke up turned on PC got on AIM and Vent perfectly tried to play Maplestory (don't judge XD i grew up with that game) but it said I had to download the game, made sense to me I just got the game a last night but just did a system restore to 2 days before so I started downloading the game it would work for a few moments but then my internet would die and the same problem that I described would happen again, and the only way i could get my internet to work on my PC was to restart the computer?
I download drivers from Nvidia website it self so i did and it said my motherboard drivers were out of date, I downloaded the drivers and installed them, the Nvidia guid said it would uninstall the old drivers and restart the computer and install new drivers but, when the computer restarted it said something about there were other wizerd installings ? and press okay to minimize the prosses so I can close those, I tried but it did some kind of loop saying again that it would unistall and install after restarting and again like last time said there were other programs running, this time i clicked exit, I went back to Nvidia site to see if the drivers for the motherboard installed, the versions matched but the site did state "your drivers are up to date" like it normally would just asked if I wanted to down load the driver as if my motherboard was still out of date?

I recently had to completely gut my computer and start from scratch, reinstalling windows xp, and all hardware. I only have a basic knowledge of computers, and their inner workings. I had my modem connected to my computer via ethernet, and i enjoyed fast browsing. Since the rebuild, i can only use the usb (and it's sloooooow!). I have learnt all i know about drivers because of this issue.

I've recently bought a new computer with a wireless card. However, the wireless signal is terrible, so I'm looking to try and get my PC plugged directly into my rooter (or by other means).
Do I have any other options of doing this, other than a wire from my rooter to my PC. Is there any other solution which enables me not have to plug into my rooter directly?? (as my rooter is in an awkward spot and has to stay there). Can I plug into an ADSL port for example? Or any other alternatives???
I'm a bit of a newbie when it comes to anything to do with networks, internet access, LAN etc etc.

We have a network in place. A week ago we switch to AT&T's UVerse and they replaced the Motorola modem with a Motorola NVG510 modem/router. There was a Netgear router behind the original Motorola but since we only needed 4 ports I pulled that out of the loop and used the Motorola. The three computers connected directly to the Motorola came right up. However, there was a switch with two computers connected to it and when the switch was connected niether of the computers connected to the switch would go to the internet. I took one of those off the switch and connected directly to the Motorola and immediately connected to the internet. Put it back through the switch and nothing.

When my Hp Desktop with Vista starts up,... the internet for everyone in the house goes out and the phones go out as well because our modem controls the internet and phone. The modem shows the DNS light blinking. When this Hp desktop is turned off I have internet and phone in the house. I just have no idea why the desktop turning on, causes the internet and phone to shut off...

I recently got a new Toshiba laptop, which works perfectly. We already have an HP desktop PC as well as a Dell laptop, which are both connected to an Ethernet router. When I got my Toshiba, I couldn't connect to the router, whether from a new Internet cable, the cable the Dell uses, or the cable the HP uses (it works perfectly fine with Wifi). The next day I got up early and tried again, and it worked. The HP was turned on, and it connected. But then the Dell wouldn't. Over the next couple days, we realized the problem was that the router only allowed the first two computers that were connected to it to connect to the Internet, but not the third one. The router itself allows eight cables to be plugged into it at a time, so I don't see why it's only allowing two computers, whether laptop or desktop, to connect. Is there a possible solution to this?It's an 8-Port Workgroup Switch, Model EZXS88W.Also, our router DOES NOT support Wifi

I unplugged the cable from her computer and plugged it into mine and it worked perfectly but when we switched it back to her computer her internet takes forever to identify and ends with local only connection how do we fix her computer?
