Networking Weird Error
Feb 24, 2011
networking error which seems to make no sense to me, i have computer 1 (tower computer) computer 2 (laptop computer 3 (tower computer1 & 2 have networked happily together for 4-5 years, sharing files and printers both ways. 3 was connected and happily joined the network but only with 2. 1 can see files on both 2 & 3, have now disconnected 3, have reset and rebooted router and both computers are up to date with software patches, i can not work out why 2 (or 3 before it was disconnected) can see 1 on the workgroup but can not access 1 in any way. i can, however, copy a shortcut from 1 through metwork places into 2 and access those files from 2. but network wizard or manual setting can not get full sharing.

I have a WiFi in my home, when this laptop is under normal load, say like streaming a 360p youtube video, all the computers in my home will experience a huge lag and it becomes impossible to surf or do any internet activity (even the causing laptop itself will experience huge pings). The weird part is that the lag is at the LAN level, it is not related to my internet bandwidth. Because when I ping my local router (192.168.2.1) with other PCs during the lag period, I get 1000-4000 ms. However, it is usually 1 ms. I tried doing a stress test on one of my normal laptops by downloading at maximum speed, the problem did not occur, there was no lag, all my PCs did not encounter that lag and I still get 1 ms when pinging the router. It is only this laptop that when it starts downloading, my network will be flooded.
Another related problem with the laptop is that every time I log off then log in and try to reconnect to my network, It will not allow me, I will have to click on the windows diagnose problem and it will be fixed saying "Problem with wireless adapter or access point".

I've had a 2Wire gateway that I got from AT&T for about 5 years. Although I've seen terrible reviews for 2Wire, I've had pretty good luck with this one. Now the Power light is a steady red and only light on. Tech support says that it's most likely the power adapter.As I understand, most what are called modems or routers today are a combination of these two, is that right? I see them in stores ranging from $30 to $200 or more, and they all say they do the same thing - almost identical wording. If it turns out that my adapter is good, what should I be looking for?

hen its wireless, it has no problems with the internet, everything works fine.But when its wired, webpages will still load, but youtube videos wont work, anything that consists of streaming doesn't work, and he cant even useI have connected other laptops to the same cord and there is no problems. so i know its not the cord and i imagine its not the router since everything still works fine with other computers.

the problem is that I'm suffering from ping spikes. When I ping my router it looks something like this:
C:UsersNiklas>ping 192.168.1.1 -n 10
Skickar ping-signal till 192.168.1.1 med 32 byte data:
Svar från 192.168.1.1: byte=32 tid=991ms TTL=64
Svar från 192.168.1.1: byte=32 tid < 1 ms TTL=64
Svar från 192.168.1.1: byte=32 tid=2944ms TTL=64[code].....

We were hit by hurricane Sandy a couple weeks ago and lost power for a week and a half. Now that our cable has been restored I noticed that the wireless internet wasn't working. The wired internet works fine to this computer but no Wi-fi.I think the problem is the routers default gateway. It's supposed to be 192.168.1.1 but right now it's 24.191.112.1 .So far I have tried:
-Powercycling everything
-ipconfig/ flush DNS
-ipconfig/ release and ipconfig/renew
-Checking all the wires are pugged in fine (They are).

I am directly plugged into the router on my computer, and it is used wireless for the rest of the computers in the house. Frequently (3-4 times a day usually, sometimes more like every 20 mins, other days not at all), the router and Network Magic will tell me my computer has lost internet connection, and browsers and any program I try to start won't be able to connect to the internet. However, I know the connection is still live because any program that was running and accessing the internet beforehand (multi player games and instant messaging programs, for example) still run fine with their connection and I can continue to play or chat online until I close that program.
Trying the 'Repair Connection' on network magic doesn't work, but unplugging and replugging the power cable to the router fixes the issue(again, so I know it's the router and not the internet)whatever reason the router is deciding to tell me it's not active and refuse access to the internet for new programs when existing connections don't show any problems.

I just got an e4200 refurbed router, and it's been working great except for one problem I'm having. I have Comcast cable with Ubee D3.0 modem. For some reason, there will be a random 4-8 second delay when going to certain websites. While this normally wouldn't be a problem, it occurs quite frequently with Google.com and we definitely can't have that. I've updated to latest firmware. Ran ping test to find optimal MTU, went with 1500. To be sure it isn't a DNS issue, tried accessing Google by IP addy and getting the same delay. The delay seems to occasionally occur with Facebook as well, at one point I couldn't even get to Facebook and had to release/renew ipconfig. I have Mac address cloned if that makes a difference.

I recently installed a very basic version of XP on my old laptop (Gateway MT3707).After hours of searching for the correct drivers, I found them, and installed them. After installing the correct drivers for wireless internet I was able to pull up the list and find my network on it.When double clicking on our wireless network it asks for a network key (also called WEP key or WPA key).Now we have a password for our network, but after an exhausting amount of tries that won't work. I not sure if that is what its looking for. In our apartment we run mac OSX, windows vista, etc., but usually the password for the network is satisfactory. I have never ran into this problem.I hate to be a noob, but I don't know where to go from here.

Having some serious problems on the networking front here at home. I have 3 PC's and 2 Xbox's that run constantly. Our Internet bandwidth is Insight's 50.0 which is 50Mb download speed 5Mb upload speed. The problem we're having is this. Ever since we upgraded from dual 20Mb lines on a Cisco RV042 to a 50Mb on a DIR-655 we've been having latency issues. I have everything turned off in the router. It's basically there to give out IP numbers and thats it. All security is handled from the PC's themselves. Bandwidth tests are fine, I sustain download speeds above 7MB/s using download managers. But pings are terrible. Xbox live is terrible, PC online gaming is terrible. Pingtest.com is terrible. Only when behind routers. I've tried it behind 3 seperate routers. The DIR-655, the Belkin f5d8236 that insight provided me, and the cisco rv042 originally used for dual wan routing. all of which are met with serious failure.
If I plug directly in to the modem pings are fine. Add a router and pings go to shit.

My laptop (Win 7 x64) can currently access all the shares on the XP computers in my home network but,although I can see it, I cannot access the laptop from my main xp computer. I haven't tried to access it from the other xp computers downstairs. I have read the guide on this site as well as 3 or 4 other threads on this subject but am unable to resolve the issue. Completing the network setup so that I can look into my laptop from this main xp computer. My laptop has a wireless internet connection but I also have it plugged into my wired home network for sharing. I will provide other details as needed. I suspect that some essential services for file sharing may not be running on the laptop, but I'm not sure.

I have been looking at ways of networking my printer in my office. The problem being that my printer does not have any kind of inbuilt networking capacity.So I thought I could connect it via USB to my router as it has a USB port on it.The router is an Orange Bright Box - In the specs for the router it says that the USB port is for file sharing, mentions nothing of connecting a printer to it

Trying to network between a Windows 7 computer and a Windows XP computer is possibly the hardest thing I have ever done.I have googled for hours and hours and none of the solutions seem to be working.I will try to explain what I have already done. Although I have done loads and I am sure I am missing some things.I have a Windows 7 laptop and for this exercise I shall call it WIN7. I have a Windows XP computer and for this exercise I shall call it WINXP.Both computers are in the same network which I have called SAMNETWORK. I have enabled permission to Everyone in folder sharing settings on WIN7. I have turned on Sharing and I have made myself discoverable with no password set on Network and Sharing Advanced Settings. Both user accounts on the XP and 7 machines are the same and both passwords are the same. I have turned all firewalls off. The WINXP computer has sharing enabled.
I have done a lot more things including installing LLTP (sp.?) and changing registry entries like Lsa/anonymous something like that (can't remember the actual directory) but I have changed registry entries as I have read elsewhere on the web and I have changed the network from home to work but that did nothing etc. etc. But everything that everyone suggests is just not working and I have been looking for about 4 hours now so you can imagine I have tried everything I have found!Anyway, my 7 laptop can see WINXP but when I click on it, it states that Windows cannot access \WINXP. The WINXP computer can see shared folders from WIN7 but it also states that it is not accessible. However, I did once get the WINXP computer to access the WIN7 shared folders. However, that doesn't even work now. I need the WIN7 to access the WINXP files. [code]

Running Windows XP Im a bit Dizzy as i can't seem to workout what's going wrong or what im doing wrong lol!!!8 Pc's on the network, all can view files etc.apart from one Pc Lets just call this "Bob1"It keeps asking for user name and password, now there's no user name or password on the giving pc, file and sharing is open and all the right ports giving. what i can't understand is that the reaming 7 pc's on the network has the same setup and files permissions, on the same subnet and can ping each other to my knowledge.So just to prove myself wrong i made a password for the pc that was asking for one on the network and this still did not work.so to cut the story short 7 pc's can search each other fine but on "Bob1" keeping asking for user name and password.

I am the CEO of a small company with 5 divisions, 2 of which are remote. There is also my home office that I wish to be on the company VPN.We can't afford an IT department, so it is up to me to ask for a network diagram (as specific as possible) that lays out all the hardware required.My plan is to eventually have an intranet web server, file server, and database server all for internal use. Our external webserver is hosted by a well-known company. Growth must be considered both in hardware and network.

I am trying to link a Windows 7 machine with a laptop running Windows XP. The workgroup on both computers is the same. On the Win7 machine, I have a couple of folders set to be shared. The first is the C Drive and the share name is C-drive. The second is Quickbooks that I have named Quickbooks. On the XP machine, I went to map network drive and in the blank typed \Remote1C-drive. It asked for username and password and just like that we were connected. But I can't see all of the files on this drive. I don't even see all of the folders - one of which is Quickbooks. So I tried \Remote1Quickbooks and Windows XP couldn't find that path even though I'm positive that folder is shared on Win7. So no matter what I try, I can't see this folder on the XP machine, I even tried copying this folder to other locations around the computer and setting up shares in hope that something would work, but it never did. So I went back to the C Drive share on the XP machine. I tried to go in reverse, creating a file and putting it on the root of the c drive (I did this on the XP machine, but the file should have actually been located on the Win7 machine. When I check Win7, the file didn't exist. So I tried the other way. I right clicked on the c drive in Win7 and created a new bitmap image file. Back to the XP laptop, that file doesn't show. But if I look at the c-drive on Win7 from the xp machine, I see several other folders and some of them like Program Files contains actual files. But some of them are just empty such as \Remote1C.

this is crazy - when i came back from out of town i tried to see if my problem still existed. it did - the win 7 laptop still could not "see" the win xp computers on the home network but all of the xp computers could see the win 7 laptop. just before sending this reply, i tried it "one more time". wa-lah, the laptop can see the other computers. this happened once before, it was seeing them, i had to leave the system and come back the next day - when i came back, the problem had returned. i did notice when i came back from out of town, my power had gone off and came back on- but this was b4 i checked it only to find the problem was still there, as just mentioned, i tried it just b4 writing this reply and the problem was no longer there. i just rebooted the laptop and as we speak, i can see all 3 of the xp computers from the win 7 laptop. i really can't make any sense out of what's going on but am beginning to think its in the modem.

I think that's what I want to do. I have an HP desktop with vista and cable high speed modem and a linkys attached to it for wireless. My laptop is a toshiba with wireless running windows 7 and I use it upstairs wireless to connect to the net. There are times I need a file from the desktop and I have to go down and put it on memory stick to copy it over. Is there any way I can access the desktop from the laptop without having to do that? Would need step by step instructions to set it up if it can be done with 2 different operating systems.

i have previously never had a problem setting up a network at home enabling sharing of files and printers with up to 4 computers with them all using all the resources/printers of each computer.i have now just 2 computers my main computer can use resources of my other computer, but this is not reciprocated.pc 1 can access pc 2 with no issue pc2 can not access pc1 unless i drop a shortcut onto the shared docs of pc2.
things i have tried:
- turning off firewalls
- running ms networking tool
- maually setting up a network
- connecting pc2 to pc3 with no issue with recripocal sharing of files/printers etc
- switching off file sharing and back on
- numerous pc restarts
- ensuring pc names/workgroups etc are correct
i am at a loss as to how i can get pc2 to start using the printer on pc1; i have just swapped pc2 for a different machine and the ame problem exists so the problem, as far as i can tell, must be with a problem on pc1 not allowing access; when you try and click on pc1 as a workgroup pc it denies access.
