Internet Connection Disconnects Frequently?

May 21, 2011

Recently came back from college to a terrible internet connection that frequently disconnects or drops in speed randomly (for all computers on network). This requires me to perform a hard reset to restore connection. This usually happens at least once a day and sometimes several. Current set up is a Motorola Surfboard SB5100 Cable Modem and a Linksys WRT54GS router.

Internet Connection Frequently Stopping

Jul 22, 2011

I am having a huge problem since yesterday. I was using my wireless connection like always and it has randomly started to stop working for brief periods of time. It's like a continuous cycle where the internet works smoothly and fast (like always) for 30 secs at a time, then it goes into 15 secs where nothing works.

Wireless Connection Frequently Dropping

Jul 23, 2011

I have a wireless Motorola modem that is hardwired to a computer that is usually off. This modem services 4 other computers in the house wirelessly and all experience the same frequent connection drops regardless of connection quality. I've had problems with this modem for as long as I can remember but it never bothered me because the problems were too far and few between; now, the connection has progressed to dropping within minutes of use.When the connection is dropped I cannot access my modem (plugging the ip address 192.168.0.1 into my web browser)The connection stays acceptable for a while after resetting but always reverts back to being a piece of crap. The connection drops most frequently when under heavy load i.e. steam downloading a game at my connection's full capacity, just only more frequently. The connection will still drop within the hour if I'm downloading anything or not.

I've tried rerouting the wireless modem into another wireless router before but it caused me new problems.Before this all started within last week, I contracted some spyware that redirected Google search links and also killed my connection frequently along with terrible slowdowns. I gave up trying to clean the system and reformatted but my internet connection still drops and it's now affecting all computers that connect to this modem. [code]

Cisco Routers :: RV220W WAN Connection Drops Frequently?

Apr 14, 2011

I'm on firmware 1.0.0.26 and I'm seeing frequent drops in the WAN connection. Most network clients don't notice the drop because it reconnects, but the X11 windows server running over a VPN drops the session and I have to re-establish it. Also, at the same time I experience a 15-20 second silence gap on my VoIP phone connected to vonage (not over VPN). Never happened on my Linksys router, but it happens many times a day on the rv220w. When the drop happens I get the errors listed below in the router log:

Wireless Connection Drops And Picks Up Frequently

Sep 8, 2012

I am trying to track down a problem I am having with one laptop. Other wireless devices on the network are not showing the same problem. Connecting to the router by ethernet resolves the problem.Over a 120 second period, the wireless connection drops and reconnects several times. Each time it drops it almost immediately picks up and re-connects. The "down time" is usually between 5 and 20 seconds.I have updated the driver for the wireless card (it was out of date) but this did not resolve.

Reading posts here - I see you typically need to see a WiFi inspector screen shot - which I have attached. You can see a couple of "drops" on the graph.

Experiencing Frequently Slow Internet Connection

Nov 16, 2011

I'm basically experiencing a frequently slow internet connection, but I believe this to be a fault with Virgin Media. Instead, I have a quick question - there are 7 computers in this house (excluding iphones etc), and the speed we pay for is up-to 50MBPS. Am I correct in thinking that this should be more than enough speed for all computers to be active on the internet without issue - including using Skype/Streaming TV etc? How exactly does a router distribute the broadband connection? This one is mainly out of curiosity, but occasionally I will find that the computer next to me has no issues streaming a TV program, but that my own computer won't even load the page.

D-Link 2750U Losing Connection Frequently?

Apr 22, 2013

I started using a D-link 2750U wireless modem-router about 2 months ago, and configured it using the given disk for my ISP (MTNL Delhi). Since then, it has never retained a connection for more than 10 days, give or take i.e starts showing a red earth light instead of a green one. I usually reset it to factory settings and reconfigure it using the same disc over and over again, but now it has started dropping connection more frequently.Recently, it developed a new disease. Connection is very unstable now. Through line, it keeps disconnecting every 4-5 minutes. re-connects and dies again itself and does not work through wi-fi at allMy hardware quality healthy as I ran a wired connection for over 3 years without any trouble before this one.

WRK54G Desktop Is Very Frequently Dropping Its Connection

Apr 8, 2012

I bought a WRK54G in 2004.  Within the past six months I bought two notebooks for my daughters.  My family added four Android smartphones within the past 45 days.  Our wired internet connection coming off the wireless router to our desktop is very frequently dropping its connection.  Seems as though one of the smartphones is snatching the IP.

Hard-wired PC Dropping Internet Connection Frequently?

Dec 28, 2011

I have a Belkin 8236-4 v2 I got from Belkin because they RMA'd a 6 yearold Pre-N that kicked the bucket. I've been having a hassle trying to get my connection stable.At first I thought it was because the DHCP was causing anything connected to the router to conflict, so I set one of the PCs on the network outside the DHCP range with a static IP and gave it the Google DNS, while this worked for my PS3(connected wirelessly) it did not solve the problem with this PC. I've looked around on the internet for the past few days trying to fix it, and tried several things, but no avail. I'm beginning to think I may need to just buy a whole new router from another company, because after reading reviews on this router I got, it seems to be a big problem for a lot of people, while it seems to happen on a number of other brand routers as well, so I don't want to give up on this thing just yet.

Windows Vista - Wireless Connection Dropped Frequently?

Mar 21, 2012

My computer is one that I built with windows vista, and for the wireless connection I am using a USB adaptor. I am not too sure what other info I need to put here.My connection used to drop frequently (around every 5 min) and I would have really slow speeds (10ish kb/s). Recently, for some unknown reason, the dropping has stopped, but now I am getting speeds of around 9-15 kb/s.

The thing that has me COMPLETELY stumped is when I plug my laptop into the router, the wireless speed on my PC speeds up to, according to speedtest.net, 5.8 Mbps. If I unplug the laptop from the router,the speed on my PC slows down to .25 Mbps, yes - POINT .25 Mbps.I have attached the tester .

Dell :: Inspiron 15-N5040 Loses Internet Connection Frequently?

Feb 9, 2012

Recently I have purchased Inspirion N5040 with Windows 7. I have observed the system looses internet connection when on Wi-FI.

Checked Ping on Yahoo & google with -t option and found few ping response and then a lot of request time outs.

I am sure you must be doubting the signal strength of Wi-Fi but I can confirm the signal strength was fine. In fact I performed ping test simultaneously on another laptop . The performance on other laptop was fine but on Inspirion N5040 I was finding too many Ping drops and was not able to browse properly.

I also, verified setting on Wireless adapter and found it is in DHCP.

Cabling / Cards :: Bridged Xbox Live Connection Frequently Disconnecting

Feb 27, 2012

Recently my xbox live connection, which is bridged through my desktop, has been disconnecting about every 10 minutes of online gameplay. Now i want to give as much information possible for the sake of everyone else. Previously when i was running the bridged connection, everything was fine. My old set up was as follows: The computer in my home office is a dell Inspiron 620. The high speed modem it's connected to is a motorola 2210- 02. Then I ran a Netgear Wireless G router (WGR614V10) which all the wireless electronics connect to. The computer in my room is a HP Compaq Presario PC (SR5807C) which connected to the wireless router using a Netgear WPN111V3 wireless USB adapter. From there I ran an ethernet cable from my Xbox 360 into the ethernet port in the back of my PC and bridged the connections. This setup was brutally effective for about 2 years. One day my wireless adapter, connected to the HP Compaq burnt out. This is when the problems began. I replaced it with a Netgear N300 Wireless USB adapter, and the HP Compaq Presario connects to the wireless router just fine and never loses connection. But when I bridged the connections between the computer and the Xbox 360, my xbox live began to go out.... ALL THE TIME.... All the of the above information remains the same except for the new wireless USB adapter (N300). I've tried everthing from restarting the computer, resetting all settings to default (both the 360 and the wireless settings on my computer), port forwarding and triggering by microsoft xbox live recommendations and anything in between. I would have figured with the newer USB adapter my live should be working better but every 10 minutes it disconnects me from xbox live. (When I get disconnected from live, the computer, from what I can tell, remains connected while the bridge encounters all the issues) At the same time apps like netflix and youtube work fine all day and I never get disconnected, only when I'm gaming (COD MW3, Halo Reach, etc.).

Cisco Firewall :: Connection Timeout ASA 5520?

Oct 25, 2011

I configured multiple vlan on my Cisco ASA5520. Everything work perfectly except RDP (3389) connections. The connections are established but but after a period of inactivity, the user is disconnected from server (black screen). The same problem happens with other type of connections (client/server), exemple : Oracle, file sharing. Before installing the ASA, computers and servers were in the same vlan and it worked well.
 
There's a notion of inter vlan timeout connection ?

Cisco Firewall :: Asa5510 Idle TCP Connection Timeout With Flags

May 14, 2012

I have ASA 5510 with 8.2.4 and 8.0.x OS and all seem to have common problem of idle TCP connections not timing out. The host to host connections are coming over VPN tunnels. I have default timeouts on all the firewalls. I have tried changing global timeouts and as well as host specific timeouts using MPF but doesn't work at all ! The problem is when TCP connections are sitting idle in conn table for days and when connection limit of 50,000 conns reach the firewall starts behaving unpredictably dropping packets or unresponsive! I need the unused idle connections to timeout which is NOT happening either by changing global values or MPF.

The user can connect if the machine storing the files is restarted but it will happen 4-5 times during the day.

TP-link TL-WN722N / Intermittent Wireless Connection Timeout

Jul 14, 2012

I've been running into an issue for the past week or so where my wireless adapter intermittently can't contact my router.When it occurs the network connection reads as having limited connectivity. I'm unable to send requests to load webpages, and videos and the like stop loading. Sometimes the network disconnects entirely. After this occurs, I can't connect again for a few minutes. My connection consistently reads as having 2-3 bars available. The issue tends to occur frequently, often every 15 minutes or so. Strangely enough, I have been able to play bf3 online for over 40 minutes without connection problems (I quit before any occurred - not sure if any would have). So far I've tried the windows troubleshooter, updating the driver to my wireless networking adapter, manually assigning my network address (tried 192.168.1.4, 192.168.1.5, etc), setting my 802.11b preamble to "Long only" and performing a system restore. I have rebooted my machine as well.

My technical specs are as follows:I'm running Windows 7 Ultimate N 64 bit edition with service pack 1. System has 8gb Ram, an i5-3570k processor and HD7850 graphics card. Motherboard is the Asrock Z77 extreme 4. My wireless network adapter is the TP-link TL-WN722N. The adapter was working fine for some time before this issue appeared.My router is an old U.S. Robotics Wireless MaxG Router. It seems to work fine with other computers in the household, although it does require fairly frequent power-cycling. Running ipconfig on the command prompt while the internet is working returns:

Cisco Firewall :: ASA 5510 - Website Connection Auto Timeout After 5 Minutes

Oct 15, 2011

Our client tried to a download a real time generated file from a website, the generation process around 5 mins, after 5 mins, the file will be started to download
 
When my client direct connect to internet, the file can be download successfully, but when pass through the ASA 5510 and using the internal IP address, a message something like "Are you sure want to logout from this web page?" appears in Safari after 5 mins, i think the time of the error message appear when a "you can start to download" message send from the server to client, the page session timeout so that make the user cannot download the file from internet as the session is not vaild.
 
I couldn't find any timeout setting in "show runn", is it possible the setting in ASDM? how can I find it and configure it?
