Internet Stops Recognizing New Connections After Increased Usage?
Feb 7, 2013
A short while ago, I had my data backed up onto a new HDD, as the old one was showing signs of failing soon. When I got the computer back, I noticed a problem where I need to constantly hit "Diagnose" in the Wireless Network Connection Status to get my internet working again. When it gets into this stage, several websites continue to work, I don't lose my connection to them. Some websites I can still connect to without a problem. However, many websites, even google, keep giving an error that the host could not be found. It appears that it stops accepting new connections until I reset the wireless card. My Laptop (using wireless) and other PC (Connected directly) have had no issues at all with our wireless router.

however recently when i check my internet usage log on my wireless company (Rogers) the usage is totally off from what my bandwidth tracker shows me. So i decide to turn off my wifi and see what happens, there has always been this weird wifi connection appearing whenever my wifi appears, then afterwards when i turn off my wifi the suspicious wifi connections disappear. is this possible that someone is using our wifi? i might just be overreacting but it has brought me to concern that if the usage continues my family will have to end up paying over $30 for extra internet use. it is very frustrating me because when i check my DHCP client table it only shows 3 connection, ethernet - my desktop which is not turned on, 2 wireless connection - my laptop and my sister's laptop.

I have recently been experiencing a problem. This started to occur after I had gotten new internet service and a new router. I now have comcast, and a new NetGear router. I also have a VOIP phone connected to the router call "AllVoi". Now, whenever I use this phone, all connections on WiFi go down as I am using it. While, when I am using any ethernet connections dirctly from the router, it works fine. It becomes a large problem when you are watching a video or something from a laptop WiFi connection.

I have a DIR-655 with both wired and wireless connections. Yesterday, network stopped working on one wired machine while using it to surf the internet and a 2nd wired machine has not worked in 3 weeks after moving it from one room to another. Wireless connections are working fine.
-2 wired systems (Windows 7 and Windows XP), both stopped working
-2 wired Xboxes - working fine
-2 laptops, wireless working fine
-1 smart phone, wireless working fine
I've power cycled my DSL modem and DIR-655 multiple times.Power cycled computer multiple times. Tried Win7 built-in diagnostics.Tried setting up static IPs.Tried filling in preferred DHCP server address.Disabled Windows firewall. [code]

I have a very strange problem on 2 (independent) Cisco 861 routers in different places.They are both configured as easyVPN servers. One uses UDP, the other TCP. VPN clients connect by using Cisco VPN client software. This cannot be changed because the customer expects it this way. Both routers have the same problem:
* the first VPN connection after a reset works fine. Traffic passes through and it is perfectly usable. I can ping the internal network interface on the router side from the client without problems.
* the second connection (and all subsequent ones from different client machines etc.) connects fine, no errors on the client whatsoever (not sure I evaluated all possible debug output on the "server" side). However, no traffic passes through. Pings do not come back from the 861 anymore through the VPN tunnel.I already enabled ICMP debugging and saw that pings are actually answered by the 861, but do not reach the client.The same seems to happen to any and all other packets as well.
* If I restart the 861 the very same thing happens: first VPN connection works fine. You disconnect, try another connection from the very same client computer, and it does not work anymore until the next router reset.I append the configuration for sake of completeness. confidential parts are represented by XXX. Some ACLs are not in use right now; I used them for testing. [code]

A client has an ASA 5505 with a base license. The version information and configuration is attached. In 8 hours, sometimes less and infrequently more, it becomes inaccessible. All connections are dropped and the only way to access the device is through a console connection. The WAN interface (VLAN 3) is connected to Verizon FIOS. The interface was set to 100 MBps and full duplex, but I just changed it to auto on both the speed and duplex to see what would happen. The LAN interface (VLAN 1) is also set to 100 MBps and full duplex It has not been changed.
The last time it happened logging was running, but nothing in the log indicated a problem. In fact, the last log entry was a couple of hours before the lockup (there's little or no traffic on the ASA while the problem is being diagnosed).

I have been using a TP-Link WR1043-ND for a while now. It is configured as a dumb switch with DHCP disabled. Every other day or so, the device stops taking connections and I cannot access via the IP address. A simple power toggle resets everything immediately. Through this, the LAN connected devices never lose connectivity, I simply am not able to connect wirelessly or access the router via web browser.The only device I connect to the wifi is my phone, so it may actually be more frequently and I do not notice due to my low utilization (and I have 3G so I don't always notice right away if I'm connected). I have a WDTV Live SMP connected to one of the LAN ports and that functions non-stop regardless of the wifi. When the wifi is "down", my phone can see the network and attempts to connect. Sometimes it times out, other times I am repeatedly prompted that the password is incorrect, even though I am POSITIVE that I am entering it correctly. Once I toggle power on the router, the phone connects fine with the stored password.
I have updated to the latest firmware (about a month or so ago): Version: 3.13.12 Build 120405 Rel.33996n My hardware version is: WR1043ND v1 00000000 The router is connected (via LAN port 1) to a wall drop. My upstairs roomate maintains the gig switch and modem, as well as handling the network admin. I simply am using the router as a switch to provide extra ports and broadcast the network over wifi in my apartment.All that said: I need troubleshooting this router and it's configuration before I consider buying a more expensive replacement (and if I go this route, I might add a small switch as well to give me more than 4 LAN ports to work with). I am also considering flashing to DD-WRT before replacing as well to see if that makes a difference in reliability and uptime.

We have an AP541N that has been deployed to replace a Cisco 1200 AP (B/G radio). The 1200 functioned perfectly in our environment. The new AP541N on the other hand seems to work fine right after a reboot but immediately starts to degrade service. Over a short period of time, the devices bandwidth degrades to the point were the wireless network is not usable. This happens with just one device connected. Eventually, the device stops accepting client connections. We are unable to get any relevant logging out of the device to diagnose the problem.

I recently changed my graphics card (geforce 9100 to radeon hd 7750) because i wanted to enjoy some simple gaming and my previous graphics card (geforce 9100) wasnt capable of doing so. (This is my pc : HP Pavilion p6100 Desktop PC series*-* HP Pavilion p6130y Desktop PC Product Specifications - c01748306 - HP Business Support Center ). Before changing the card i uninstalled all nvidia related drivers (both in control panel and device manager) because i heard thats what youre supposed to do.
I successfully changed my graphics card (i think...) i can run all the games that i couldnt run before but.. I am having trouble connecting to the internet after changing the card. it seems like my computer isnt recognizing the inernet network. i know the network is fine because im writing this w/ my itouch which is connected to the network wifi. When i right click the red X icon w/ two computers and click "connect to a network" , it says "windows cannot find any networks" and i have no network options to choose from. Is it because i uninstalled drivers related to the network connection..?

We had 1.5 Mbps, but we just upgraded to 8 Mbps. Right away we noticed that we couldn't connect to the Playstation network on the PS3, and loading Google would take several tries. In some cases you couldn't even refresh the page to load Google, you would have to open a new tab. We would have bursts of good speeds from online speed tests, ranging from 8.6Mbps down to not being able to load the test, and everything in between. urls... live in Wisconsin and my ISP is Centurylink (formerly Centurytel), a technician came over yesterday and checked our box outside and inside and said that it was our Margin (db), if I remember correctly. Here is the info from my router: [code] The technician ended up lowering our speed to 6 Mbps, and said that everything looked good, and left. The Margin (db) was at 7.3 inside and 9.7 outside before he lowered it, and he thought that if we could hit 10, we would be fine. If that's the case then it seems like the margin is not the problem. If we are using too much speed could we set QoS on a router (would need a different router) to limit the bandwidth?

I have started to notice an increase in traffic from all my LAN workstations to the multicast address of 224.0.1.20, all with the same destination port (79). IANA shows this address as reserved for "experimental testing". Are there any typical applications or protocols that use this multicast address? My first thought was malware running on the hosts but it's a little tricky to prove.

Have been experiencing speeds of max 2.5 Mbps for transferring files between Windows 7 machines connected wirelessly to a Billion 800VGT router. A speed of maximum 18 Mbps was achieved. No matter what I did to adaptor settings it was the best possible. Have 6 wireless machines which I cross checked multiple times using Lan Speed Test by Totusoft.I then disabled the wireless security (WPA-PSK) on my Billion 800VGT router and secured the network by using the Wireless MAC address filter. My speed immediately increased to 11Mbps between wireless machines. Speeds to machines on fixed lan increased to 26 Mbps.

I came across a interesting symptom. Refer to the following topology.
host 1 <-> R1 <-> R2 <-> FW<-> host2
host 1 is configured to send syslog to host2, however due to firewall ACL is not configured, this has caused a spike to 99% in R1 which already has 70% - 80% cpu.
My questions are :
1) Even if the firewall is sending RST back to host 1, it should not caused an 20% cpu increase in R1 cpu. Why this is so? Router model is 3620.
2) How do i prevent this from happening in future? This could potentially allow someone to send random traffic to hosts and cause network performance issue. Is there a way to turn off the RST response from the Firewall? This is an Cisco ASA.

I just needed more insite into the function of the ip tcp adjust-mss command which can be used to adjust the MSS value in the tcp syn packet which passes that interface. But here is a question which I had. Consider that i have two sets of systems in my LAN one with an MTU value of 1300 ( MSS 1260 ) and with a MTU of 1500 ( MSS -1460 ). If I go ahead and put an ip tcp adjust-mss 1456 (for reducing the packet size from 1500 to 1496) on the WAN . Does the command only lower the MSS for the set of systems which have 1460 or will it also increase the MSS in the tcp syn packets send by systems with MSS of 1260 ( which can potentially break some communication ).

In the company I work for, employees' internet traffic is monitored, and if you download too much, you get a warning, and later there might be more serious consequences. But they don't tell how many kilobytes are too much, and they also don't tell, how much of your "kilobyte budget" you have spent already. So I want to be able to monitor my own internet activity. However, all the programs I found so far watch the whole traffic going through the network card, which, beside the internet usage, includes LAN and mail server communication, which don't count. So, I'm looking for a free portable program that can monitor specifically my browser's internet usage, i.e. the number of kilobytes sent and received by the browser application. It is imperative that the program should be portable, or at least installable without administrator privileges, because I don't have that.

I'm having trouble setting up a wireless internet connection for my computers, I connected the patch cable from my modem to a wireless router, then connected to that network with a usb for my computer.I was able to connect to the network, but couldn't seem to actually get into the internet. Is there any solutions to this?
When doing ipconfig /all, the message I get is:
Windows IP Configuration
Host Name . . . . . . . . . . . . : Victors

I have 4 laptops (WiFi), 2 desktops (LAN), xbox (LAN), and dish receiver (LAN) that are all connected to the internet using the method between the brackets. Recently i am running out of bandwidth, and what i am looking for is a freeware that i can install in one of the computers that could tell me which IP or MAC address used how much internet.I have read several articles: some articles point me to softwares which only monitor the computer that they are installed. Other posts argued that such thing can only be done through the main router. I know my router doesn't have such feature. I use SMC router.

I am trying to figure out how I can see what my monthly total bandwidth usage is. I have been trying to find a way to monitor my internet usage so I can make an informed decision on ISPs. one has a cap but allows ESPN3, the other is the opposite on both accounts. everything I have been finding look like good products however they all look like they are for an individual device. I have about ten devices and not all would have the ability to have these programs on them. I have and old xp machine that really is only good as a paper weight, If I had to I could make it a proxy but before I do that and create a major bottleneck I wanted to see if there were any other options

I have a small Network at my office, all done by myself with my limited knowledge. I have 9 systems connected thru physical LAN and 1 laptop connected through Wireless (from my internet router)I have distributed the internet connection openly, not using a proxy server. Anyone plugs in will get Internet on their system through the DHCP.Recently I found that internet usage been crossing the limits.sniff/monitor internet/bandwidth usage system wise.I have a internet router (Linksys/Cisco WRT 120N) from which the cable goes to an un-managed 8 port switch.I have three different areas in my office, so I pulled single cable to each of these areas and there I used another un-managed 8 port switch to distribute the LAN to the systems.

Whenever I try to download anything with my computer, my Internet stops working and I must restart my computer in order to get it back. This only happens with my computer, since others in the house dont have the same issue.As strange as it may seem, this doesnt happen with Bittorrent. Only with regular downloads.

It's fairly hard to explain what happens but basically, say I'm playing some type of online game, all of a sudden anything server sided such as HP amounts, damage amounts, etc. just disappears but the animation runs fine such as attacking being hit, etc. All of a sudden it'll jump forwards and I'll take any damage and do any damage that had been happening until the issue started. This happens constantly and it's really frustrating but on top of that my internet will slow to a crawl..Say I'm trying to send a message on Skype, it won't send for the longest time and I won't be able to recieve any or even open a new webpage until the problem fixes itself.'ve looked around a bit and thought I fixed the issue, I'm on wifi and multiple devices are connected but not always in use, and the forum I found suggested an ip conflict and said to open up command prompt release the ip with ipconfig /release and then renew it with ipconfig /renew.
