Network Connection On One PC Interfering Rest?
Oct 11, 2011
Whenever I connect to my router via wireless, It slows the network to a crawl, and I can't view websites through the same PC.Now, It only started a few days ago, and I can't find the root cause. This happens in Windows 7, however, it works in Linux with the same PC, in the same location, so it can't be the wireless card going bad. When the computer isn't online, however, everyone other connection, including smartphones, my wife's laptop, PS3, all work. I've tried updating the drivers, flushing the dns, resetting the winsock, ip release/renew, haven't found anything that works.
I've also run numerous virus scans, malware, spyware, and registry scans. The only thing I can think of is something is trying to send a lot of traffic to the router. So far, Malware Bytes, Avast, AVG, and Spybot haven't picked up anything, and I can't find the traffic leak via Windows Firewall or Comodo.
OS: Windows 7 Home Premium
Wireless Card: Asus USB-N13 using Ralink drivers
The only thing I haven't tried is connecting through my ethernet card, but it's not feasible at the moment to move the desktop to the router.

I am currently connecting my PC to a mobile phone as a Wireless Access Point to give that PC access the internet. I also have a small home network, with one other PC and a Game Console. I own a Linksys E900 Wireless-N300 Router. My problem is this. How do I share that internet connection with the rest of the home network?To the best of my knowledge its not possible to connect my mobile phone directly to my Linksys E900 Wireless-N300 Router.
So my alternative idea is to connect to the internet via one PC, set up that internet connection as "Shared." and then allow the other devices on the home network to connect thru this. My question is how do I set up my Linksys E900 Wireless-N300 Router to allow my other PC and game console connect to the internet? Bridge Mode? PPPoE?

I recently bought a Polk 6000 soundbar that has a wireless subwoofer.Whenever I try to stream netflix wirelessly to my tv I keep losing the netflix service. I had no problems with streaming before connecting the soundbar.I have been reading customer reviews on the soundbar and many have suggested to bring up the router's configuration screen and change the channel setting. Currently both are set for channel one. I have uverse 12mbps. How would I go about changing the channel? and will this cause any problems with my other wireless devices in the house?

My home network is up to now all hard-wired, nothing shared etc.I just got an ipad though, so do want to have wireless available now. I would like the ipad wireless router to be isolated so that the desktops run no risk from getting a virus via the ipad wireless connection.So, I was going to buy another router - would I be able to plug that into the wired router, and the desktop also plugged into the wired router, would that keep every part of the network isolated from the others?

ATT dsl modem into a 16 port netgear gigabit switch into dlink 615 Some computers are hardwired two are wireless All was working well before d-link with the linksys When im on a wireless computer i cant see the other computers hardwired to the network through the switch. When i take a wireless computer and plug it directly into the switch it see the rest of the computers fine.Something screwy is happening between the switch and the dlink router not allowing me to see my shared folders and printer over wifi.

My boss has a WRT150N that he wants to add to our network. The line coming into this router comes from a switch which all of our other computers/ printer are connected to. The router transmits the internet fine, but I cannot access the LAN when connecting through the router. The printer has a static IP. All internet traffic comes through a hardware firewall which is between the outside world and the switch. When I connect the line going into the router straight into a computer, the computer can see the network/print/whatnot fine.

Limit his bandwidth. but he will only be staying till the end of summer. The new roomie then might be a torrent monkey.Completely shield my other computers from his sight, so to speak. Like I said he's not a hacker but the new roomie might be.
I'd like the router (linksys WRT54G v3 runner latest linksys fw) and the rest of my network (main PC and media server) to be resistant to at least a script kiddie, and hopefully against a intermediate hacker.I'm currently using wifi with WAP2 personal as the router security.

Can the Nexus 7000 provide NTP to the rest of my network? Can it be an NTP server? I have the followign ntp configuration on it, and have used the commit command, but it seems to be ignoring any NTP requests from other devices. [code]

I am new to configuring WLC's. Our small business (5-15 wireless devices + 15ish wired) is trying to use a hand-me-down WLC and AP for our office wifi. We have a WLC 2106 directly connected to a 1231G-A-K9 via the WLC's port 8 POE. I am aware Cisco does not recommend this method, but we do not have a configurable switch at our disposal. We do not need separate VLAN's therefore I have left everything untagged. The AP has a static IP setup to allow communication to the WLC since it did not pull one from the WLC.
The AP is getting the correct network information and is showing up on the WLC monitoring page. I am able to connect to the new wireless network and able to ping between devices connected to the same AP. Now here is my question/issue. I cannot get communication from the WLC/AP to the rest of our network via an unconfigurable Netgear switch (FS605v3). After connecting an open switch port from the Netgear switch to port 4 on the WLC, I am lost. I tried giving port 4 on the WLC an address on the office network, but I receive an error stating "the IP information conflicts with another device".
Here is what I have setup on WLC
Virtual - 1.1.1.1
MNG IP-192.168.10.10
AP MNG Ip- 192.168.10.11
Subnet - /24
Gateway - 192.168.10.1
DHCP - 192.168.10.250
DNS - 192.168.10.250
Static Address on the AP's fa0-192.168.10.15
Attempted port 4 setup on WLC
VLAN identifier 0
IP- 192.168.10.25
Mask - /24
Gateway - 192.168.10.1
Port - 4
Our office network setup:
Subnet - /24
Gateway-192.168.10.1
DHCP - 192.168.10.250
DNS - 192.168.10.250

I have 12 wap4410n to enable wireless connection to a school building with 3 floor. I planned to configure one as a Access point. My doubt is in which AP mode i have to configure the rest as WDS Bridge or WDS Repeater other mode. In each access point i have Ethernet connection to the switch.

I have a dlink DWA130 wireless N adapter connected and working. But AOL Dialup takes over. When disconnecting the phone line for AOL, there is no internet connection. The adapter is connected and has great signal strength. What can I do to make the wireless adapter work independently from AOL dialup?

I've hot connection issues with my wireless Mac keyboard for a while. I've brought the computer in to Apple to see if the problem lied there. They replaced the Bluetooth adapter, and I got a new keyboard, but I still have the same problem. I've moved the router as far from the computer as possible (but it's not that far). Since the E3000 is dual band, I'm wondering if the 2.4 GHz channel is interfering? My friend has a Bluetooth keyboard and a wireless router on his system, and he never has connection issues.

I am using a Cisco 1921. I have created 3 L2L VPNs. Although I can get the tunnel of all 3 up, I can in the case of one ping the LAN IP of the router, and the 2nd on from the peer subnet, but not the other way round. If any one can make sense of this that would be great.. I can see the ACL being fired, Annoying as the first VPN is up and working fine, in both directions.. Would be really grateful of a fresh pair of eyes..
NAT blocking ACL working fine too..

Extended IP access list 101

Relevant Topology:
(Corporate LAN: 10.10.0.0/21) > (Catalyst 3560 L3 Switch: # ip routing) > (10.10.255.253/30) > (Cisco 1921: edge router) > ISP
One-to-One NAT statement in edge router:
# ip nat inside source static <inside local ip> <inside global ip>
Packets destined for our branch offices across IPsec Site-to-Site VPNs, originating from the above inside local IP, change their source address (at the edge router) to the above inside global IP, forwarding traffic destined to branch to our ISPs gateway, instead of over the VPN tunnel.
After establishing a remote IPsec VPN connection, via Cisco VPN Client, I am able to ping the inside local IP specified above with no issues (the router sends the traffic sourced from the above inside local IP before applying the One-to-One NAT statement).
Relevant configuration:
Remote VPN ACL:
ip access-list extended REMOTE_VPN_ACL
permit ip <ip local pool subnet> 0.0.0.255 any
permit ip 10.10.0.0 0.0.7.255 any
Site-to-Site VPN ACL:
ip access-list extended SITE-TO-SITE_VPN_ACL
permit ip 10.10.0.0 0.0.7.255 10.10.12.0 0.0.0.255
permit ip 10.10.12.0 0.0.0.255 10.10.0.0 0.0.7.255
[code]....
If I remove the One-to-One NAT statement, both the Site-to-Site VPN and Remote VPNs can communicate with the relevant inside local IP. With the One-to-One NAT statement active, only the Remote VPN can communicate successfully (as the NAT statement change the packets source address to the inside global IP).
Why is the One-to-One NAT statement only applying to packets destined for our Site-to-Site VPNs, and what is the appropriate way to prevent this?

I am facing problem with ACE configuration. I want to redirect 443 traffic to my Proxy Server. But I am not able to do this. I want to redirect only subnet 192.168.80.0/24..Then only it is working but I dont have to have this policy to be applied on all the users only one subnet I want to have under HTTPS policy.
how can I apply the policy only on specific subnet so that port 443 traffic can be redirect and rest of all subnets can go direclty to Internet.

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 two networks 192.x.x.x and 10.x.x.x, Configured at my Astaro 220 UTM, which obviously where the gateway is, from my UTM I have 3 isp connected which is the source for my internet. Now from astaro to my core there are two connection, 1 for the 192 network and the other is for the 10 network and from the core there goes my LAN where switches are cascaded.My problem is i'm having slow connection accessing from 10.x.x.x to 192.x.x.x network vice versa. what are the possible solutions is applicable, or the things I should check. plus I can't access(configure) my switches which is on the 192 network from 10.x.x.x. network through web.

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

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.

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.
