How To Repair Network Connection
Jun 4, 2012
Every time I start Windows XP, I see an icon of Internet connection being established, and then a connection error icon with a pop-up window. When I click on it, I see the connection window with a notification that no IP address has been assigned.In order to get an Internet connection, I have to click "repair" every time. I have downloaded and used TCP/IP and Winsock repairs without result. I use WIN XP SP3 and run updated Avira and Comodo. I am aware of damage left behind by deleted malware but don't know where to look.

My error message states that "Windows could not finish repairing the problem because the following action cannot be completed: Registering with DNS".I have no internet connection on my HP PC, which is why I am typing this on my laptop.On the HP I am running windows xp with sp3.I connect to a cable modem provide by Time Warner.This problem started yesterday, so I have been utilizing both computers with one internet connection, or plugging and unplugging the cat5 cable.I have run Microsoft Essential Full scan, as well as Malwarebytes's Anti-malware.Now I ran both of those in Safe mode, and picked up no bugs. I have Avast as my antivirus software, and the message I receive on that is that "Avast will not be able tp protect mail/news (error 10050). I am unable to turn on the web shields for Avast.I have manually entered the IP addresses into my HP from my laptop, all the way thru DNS servers.It still won't connect.I tried using the Internet explorer diagnostic tool, and it came back and said that I have a winsock issue.

Using WRT110 router, running XP, SP3 on both laptops, one a Dell and one an old Toshiba. Never any problem with the Dell (and Gateway before that), nor the iPad, Acer notebook, etc. However, the Toshiba keeps losing the connection to Internet (even though the icon says the connection is excellent). DH has to continually Repair in order to connect. I even reformatted the Toshiba, thinking it was something in the Registry. Now that it is back up and running (and all programs updated), it STILL periodically has to be repaired in order to connect.

I have a WRV210 router setup with WPA personal-AES encryption...SSID is turned on. The issue is that workstations lose connectivity to the internet and to a mapped network drive on the server. When this happens I find that the wireless status shows "connected", along with excellent signal strength. It never happens when logging on, just after so many minutes. The simple remedy is to repair wireless connection but we would like to not have to resort to this behavior every day. Further, I found that within the repair connection sequence that deleting the address resolution protocol table, brings the internet and the ability to access a mapped network drive back. I even used a program called arpfreeze to assign static ip's to the arp table and I still had to repair wireless connection. It does not matter where the workstations are placed, whether sitting 50 feet away or 5 feet from the router, the workstations lose the ability to access internet and mapped drive while showing "connected" and excellent signal strength. Otherwise, we are looking at running ethernet cables through the building (Not easy).

Recently acquired a Dell Inspiron 6000. I had the hard drive clean off and Windows XP reinstalled. I have no problem connecting to the internet when I power up if I go through "repair connection". I have to do nearly every time I power on. How do I get it to stop? My other Inspiron had no problems connecting.

Yesterday I bought a new wireless adapter (Belkin Surf Micro, it was the only one for sale nearby). I installed it from the disk, and it worked for around a minute, then... nothing. This kept happening every time with several reboots and reinstalls inbetween.I thought maybe the adapter was faulty, so I installed it on my Mums laptop. It worked great.I have tried flushing the dns, and some other command prompt based things suggested on other sites, but to no avail.But here's the thing that strikes me as funny: Even when it connects to the internet for that minute or so I cannot ping the router, even though it says on the router page (viewed from another computer) that I am definately connected to it. I also cannot ping google or anything but myself.

Wireless internet connection stops working after anywhere from 10 minutes to two hours, a message pops up telling me it is "impossible to connect to my preferred wireless network", and then it fails to detect any wireless connections at all. The strangest thing is that when I try to "repair" the connection, which used to work, the computer immediately shuts down and restarts itself. It also seems like when I attempt to download something, like a movie for example, the connection fails right away, while if I'm just surfing the web it usually lasts around an hour before stopping. And when I restart the computer again it works perfectly fine at first, like right now, but eventually does the same thing.

I have a computer that is running Windows XP and is using a Linksys wireless card and their connection software. (It's not my computer, and I can't recall the name of the software.) The computer can't connect to the internet, but it can connect to the wireless network. When you try to repair the connection you get back that the computer cannot refresh the IP address, and thus repair the connection.A few extra things, the owner seems to be under the impression that another computer has kicked him off and has somehow broken his connection due the fact that it is used for gaming. These problems occurred when said computer had no internet connection at all. (Wired or wireless, everything was unplugged.) I just would like some kind of verification of the fact that another computer, under general circumstances, can't break another's connection out of thin air. I have tried resetting card, routers, and some other things. I am working on trying other wireless receivers on the computer and a different router tomorrow. I will update when that is finished.

My ISP is Sky who I use for phone calls and internet, the line to my my house was installed by BT several years ago. I live in a fairly rural area and have never had more than a 1.5mb connection.
Two months ago a neighbor who was repairing his guttering accidentally broke the main phone line coming from the pole directly to our house (the ladder he used was left unattended and it fell over catching on the wire). The line broke in the middle of the length that runs from the pole directly in front of our house to the connecting shackle on the house fascia board, on the first floor.
I connected the broken wire back together, I only have one line in, so all that needed to be soldered were the white and orange wires. The other colored wires I cut flush. The remaining three steel core wires i used as holding wires. Everything was heat shrink sealed, insulation taped up, heat shrink over the whole lot and then more insulation tape put over the whole join, allowing around three or four inches over run at each end of the join. Afterward I did a quiet line test (17070 option 2) and the line was good. My internet speed was as per usual, 1.5mb.
Last Wednesday I was checking my email and web pages kept timed out, i logged on to the router and checked the speed I was connected at. My speed was 560kbps / 56k. After several router resets the speed was still not any higher. I did a quiet line test again and there was a considerable amount of line noise.
As it had rained a few times since my repair to the wire I thought it best to check to see if any water had gotten in. Unfortunately, even with all the insulation water had indeed got in. There was a score mark on the cable and that was the obvious route of entry. Upon opening the repair back up I could see the copper wire inside the orange line had turned black. I had to cut back the damaged line about 10 inches total, to get shiny copper cable and remove the scoring on the outside of the cable. I re-joined the line as I had done before. A quiet line test was good, but my internet speed remains at 560kbps / 56k.
I bought a new ADSL filter, and have tested the router directly in the master test socket without my phone extension, no difference in internet speed at all, and like I said the quiet line test is perfect.
Before I bite the bullet and get BT to come and renew the cable (which I am going to get done, when my neighbor can afford it) is there anything that I could have overlooked, or is it possible that the water has damaged something i.e. the Sky router or other parts of the cable?

I have an Acer 7750G, running Windows 7,connected to our home network using a Dynex router. At the moment this is the only laptop in the house that is having problems with connectivity. Starting yesterday, it only connects intermittently. When I run diagnostics, it says the following problems have been fixed but it either solves the problem for a few minutes only or not at all: "Problem with wireless adapter or access point" or "Default gateway is not available".
IPV6 connectivity also shows 'no internet access' and sometimes IPV4 reports no internet. I've unplugged and rebooted the modem and router a few times but that hasn't solved the problem.
Edit: I ran troubleshoot again, and it says the following issue is not fixed: "Wireless Network Connection 2 does not have a valid IP configuration".

I use my desktop for streaming media throughout the house. I found it was causing lag for gaming most likely because it was taking up all the bandwidth for the router. We had a 2nd router laying around as well as a 2nd wireless adapter so we set up a 2nd network that was not connected to the internet for strictly media streaming.I attempted to change the network settings so the internet connection appeared as a public network so that streaming of media was hopefully diverted to the non internet wireless adapter.I want a faster way of transferring large video files from my laptop to my desktop. I recently bought a crossover cable to do this through direct connection.Both use the same user name and password as well as run the same win 7 pro however the desktop is the 64 bit version. I set up both ipv4 with the same addresses.When it has worked I am only getting a connection speed of just over 10mb and once I connect the crossover cable between the computers it knocks out my internet connection on the wireless card.

I have a problem with my home network (diagram attached below). I sporadically lose connection between my Router and the devices behind the switch. I have replaced the Ethernet cable between the 2 so I don't think the problem's there. It will work for a week or so, then just lose the connection. I then try a combination of rebooting all of the devices on the network and/or unplugging and re-plugging the cable connections and sometimes that works. It's a relatively new router, but can a router be "underpowered" for pushing a signa

There is a device which is connected to the PC via Lan. I have an exe file which is supposed to get connected to that device and perform some operations. However, the problem is, the exe file tries to connect to the local host ip address 127.0.0.1 and i cant change the ip since it's been coded.So, I'm wondering if i can use the device connection (which already has a different ip like 169....) as a local host connection. So whenever it tries to connect to the loopback 127... it automatically connects to the external device.

I have a windows vista SP2 laptop, with an Intel wifi link 5100 adapter and a Realtek PCIe Family LAN adapter. From some time ago, I'm having this issue: each time I want to change network (from my job's to my home's, for example) I have to disable/enable the adaptors. This was not needed for over a year and so I own this machine, and I think It might have something to do with a network drive some IT guy in my new job installed

I have noticed a few times over the last month that my PC would not load pages due to connection problems. If I hover over the Network icon, it say that I am not joined to a network but within minutes, it reconnects itself. I use http://www.scan.co.uk/products/zyxel-pla-4201-500mbps-mini-powerline-adaptor-twin-pack power adapters and they "appear" to work well with good speeds as I download and game online alot. I have noticed that today the problem is really bad. It loses its connection every 5 or 10 minutes and then reconnects itself as if nothing has happened. I tried using my iphone on the wireless and it also seemed to have dropped out on connection. I have tried resetting my router too but with no joy

I have a Win 7 laptop which keeps dropping its network connection. I have changed the power management option on the network card so it can't turn itself off, but it still goes to sleep after a certain amount of time.I've also tried with a different docking station and network cable in case that was an issue, but the same thing happens. Event viewer does not reveal the cause of the drops.

I have a print shop that runs several computers on one network off of a single adapter. Last week the boss and I went out of town for some off site training leaving a single employee in charge of holding down the fort. When we came back we ran into a whole slew of problems not the least of which being that one of our graphics computers doesn't seem to want to recognize the work network anymore. It seems like the employee who we left (who, of course, "didn't touch anything") must have disconnected the computer from the network and started a new one as it is connected to one simply entitled "network". The issue I'm running into now is that when I check the network list the work network is not showing up at all. I've checked and I can ping the other computers on that network, they are all connected to the same network adapter, I just can't seem to get this one computer onto the preexisting work network.

So I've had this problem ever since I bought my computer. The only wireless connection that I am able to connect to, is the one in my home. If i travel anywhere else, my laptop refuses to let me connect. The thing is, my laptop sees the connections, but when I click "connect", the box closes and nothing happens. The laptop seems as though it doesn't even try to connect to the network. Everything remains the same, yet when I come to my house, it connects automatically. Now if I click "Add" on the network config. it won't even let me add a network to my computer or anything. I click the "Add" button and nothing happens. I am running a Windows XP.

There is a computer at a job location that MUST have internet access, but the property manager at that location does not want the computer to be in their network for security reasons. Is there anyway we can create a new network and still have internet access with out being in the property's own network? Is it as simple as just creating a new network?

I'm looking to improve my connectivity,as the internet drops out a few times a day.Let me explain - I hope I'm correct in my assumptions.Every few hours, my PS3 will have a DNS error, and upon checking my iPhone, I notice that it's switched from wifi over to 3G and there seems to be a loss of connection. I cannot reconnect to the internet until I've restarted my router, or 'forgotten' and rejoined the network.
Additionally, we have an Apple TV, and connection drops out about 3 or 4 times every hour, which is very frustrating when trying to watch a movie.
