Keep Losing Internet Connectivity?
Aug 29, 2012
ISP : ShawPC >> SMC Modem/Router >> Netgear Router >> PS3 and Denon Stereo Receiver ( Both hardwired to Netgear Router), 2 Laptops and 2 Phones connected wireless- The reason I do not use the SMC as a router is because I was getting terrible wireless signal- When everything is working properly I am getting great speedsroblem : I keep losing internet connectivity. On the wireless devices I still have have great signal strength but no connectivity. I need to run netgear genie oripconfig/release/renew to get it back. It always comes back but this is annoying.It also does this on the PS3 and Denon which are hardwired to the router..as with the other ones if I reset the router or do a connection test on the PS3 it will fix it. Finds IP but no internet connectivity.My PC has also started to lose connectivity and I need to do a ip release/renew and it comes back fine.The fact that this is happeneing on my PC would lead me to believe that it may be an issue with the Modem/router. Are there some settings I need to change on it since I am only using it for modem purposes? I have disabled the wireless on it but I don't think that would be the issue anyways

Noticed the last couple days that pages weren't loading on my laptop. Looked at the network status for the laptop and noticed that my network speeds would fluctuate from 54Mbps to 1Mbps, and various speeds in between. I had never had this happen before (I've had this router, a Linksys, for about 6 years). I thought maybe something was going on with the laptop. Grabbed my wife's laptop and she had the same issue. So, I checked the wired towers - their speeds are running at 100% all the time, no fluctuation. So, it has to be something with my router, but I'm not familiar with how to diagnose, etc. The router has a 3rd party firmware (DD-WRT) flashed on it, in case that matters. But I've had that on there about 4 years, nothing new. I've done a DHCP release and renew.

I have a DIR-625 router that has been acting odd lately. Several times a day at random my devices (laptop, android phones, PS3) will lose internet connectivity from my wireless network. They say they are still connected to the network but I am unable to access the internet or even the router config page. Everything works fine on Wired LAN computers. The only way I can fix it is by unplugging the router for a few seconds. I have had the router for over a year now without this problem. Seems like it may have started when we got our android phones.

I am having an intermittent problem with my network connection dropping out for no apparent reason.When it drops, I still see the lights blinking on the NIC card, but cannot pass packets even to the router.Windows does not report the connection or the cable as disconnected when this problem is occurring.The problem will persist until I disconnect and reconnect the CAT-5e wire, or disable and re-enable the NIC.As soon as I do one of those 2 things, connectivity immediately returns (and works for another hour or so).I am running a legitimate copy of Windows 7 Home Premium 64-bit on an HP Pavilion.All of the latest Windows updates and the latest firmware drivers are installed.My ethernet connection is a wired Local Area Connection with a static IP address, gateway and DNS.The IP address, gateway and DNS settings are accurate and work for several other computers here.[CODE]

I have an issue with my current network where every couple of hours I will lose my connectivity and it will not come back unless I do a power cycle on my router/modem. I originally thought the issue was with my router, however I'm beginning to think it's an issue involving the modem. I've tried two different routers and this happens on both. My main router is a D-Link WBR-1310 (crap I know but it was free) and has lasted for years, and my modem is a Toshiba PCX2500 from Time Warner Cable. The second router I used to test this was an older Linksys BEFW11S4. I was going to replace my router, but when I saw that both of them reset after a few hours (today was only 5, last night it was connected for over 8 hours as I slept). I ran an IPCONFIG /ALL when I was connected with internet and when I was connected without and the only three changes were: [code]

I have a UC520 in a building with several IP phones. We installed a WLC526 and two AP521's for seamless roaming of cordless phones. THe phones work great with no issues. When I am running a ping test on a wireless laptop, i keep loosing packets. It looses connectivity randomnly. DHCP is given via Windows 2008R2 server. Have a cisco 2948 switch also in the mix. THe AP's are connected directly to teh front of the UC520. Why do phones work perfectly and not data?

our autonomous 1252APs. It loses network connectivity irregularly and ends up disconnecting everyone. It may stay up from a few days to a few weeks. I don't see any log messages that give any clues to why it is doing this. We have 30 of these working worldwide (on the same software level and same config) and this is the only one having the problem.
Things I have tried: Changing software levels - there is a code level where it didn't seem to have this issue, but I can't run it because then I'm unable to monitor it in our monitoring system. Swapping out wireless access pointsRe-terminating the cable on the AP side, it was really difficult to get the network cable into the AP while swapping it outBlocking a company test piece of equipment from connecting using the mac address filtering (it connects with one of their test IPs - weird) – I still see it connecting though I don't see high utilization on the switch port when the issue happens I had a few cases open with TAC, and they were unable to find anything wrong - gave them sh techs of prior to the event and after the event. It was one of those where the tickets were open for a weeks with no updates.

Receive Buffer Size on the NIC is 64Kb (512 buffers). Receive Side Scaling on. 128 Transmit Buffers.Interrupt Moderation is turned on. Magic Packet features are turned off. Optimal Performance enabled.NIC Speed and Duplex are set to 100mbps Full Duplex wherever possible (automatic was also tried).802.1X authentication (EAP or PEAP) is disabled. Auto connection logic is disabled.Connection routes through two switches into a Belkin router; other devices on same networks unaffected.Much of my data is stored on a Network Attached Storage device, with UNC shares mapped to drive letters.Other Windows, Mac and Linux devices connected to the same NAS device have no problems staying connected.When the issue occurs, I can't ping the gateway, do DNS lookups or pass any packets as far as I can tell.I have tried swapping out the CAT-5e cables for other cables and even ran them through a cable tester.
Network fixes I have attempted from the OS level so far include:
~ Switching the dynamic port range to start at 10,000 and run for approximately 54,000 ports
~ Systematically reviewing every running service to make certain that only the essential ones are on
~ Disabling all NIC stacks except Client for Microsoft Networks, IPv4, File and Printer Sharing and Comodo
~ Attempted connections with Comodo turned completely off and its NIC driver disabled
~ Attempted rolling back the RealTek driver to an earlier one from the same family and device line
Using netsh I have tried the following settings:
~ netsh winsock reset catalog
~ netsh int ipv4 reset reset.log
~ netsh int ipv6 reset reset.log
~ netsh int tcp set global rss=enabled

I have the model AE1200 usb adapter and its been working great for over 6 months, but lately it has been inconsistently working. It has stopped working then i have to reset the adapter and then it will work for a little bit and then it will do it again. is this a common problem or is it likely my adapter is failing? Is there an update that i am missing?

We are implementing a WLC infrastructure in our company following the below scenario:
- WLC 5508, OS 7.2
- APs AIR-LAP1142N-T-K9
- 3 Wlans (1Open w/ Web Auth, 1 WPA2 and 1 802.1x)
Issues:Everything seems to be fine, but some users loses connectivity (when connected to 802.1x network) at least 3 times by day.
- I cannot see anything at WLC logs concerning the association/deassociation of any of these users.
- Only strange line in the logs is "RADIUS server 172.21.44.50:1646 deactivated in global list" (authorization server config)
- Also I see some "Coverage hole pre alarm for client" but that doesn't look like a problem...

I recently purchased a Belkin F5D8053 N Wireless USB Adapter after my 6 year old adapter was unable to see my home network in the network list.
I installed the software but the adapter wouldn't connect to my home network so I reinstalled and updated the driver, still wouldn't work. Finally about 2 hours later it just randomly connected. Now it has been frequently (1-2 times a day) losing connection to my home network for around 3 hours, it can see a dozen networks in the list with full signal strength but won't connect to any at all then connects to my home network again several hours later.
I have switched between the Windows connector and the Belkin one and tried all 6 USB slots with no luck. I contacted Belkin support and they told me to try the device on another computer and see if the problem still happens but I don't have another computer to test it with.
I suspect this is a problem with my Windows installation rather than the hardware or router as my old card would freeze once every couple of days and was only fixed by powering off my computer as Windows was unable to kill the process to restart it.

Issue with Linksys E3000 router (firmware 1.0.02). I'm experiencing issues with the following wireless connections:
-iPhone 4G (wife's)
-iPod Touch 2G
-PC with wireless connection (non Linksys brand adapter)
-Acer NetBook (non Linksys brand adapter)
The issue is the connection gets interrupted and dropped, but the devices and the router DHCP clients table show the connections are still present. By interruption, I mean no data traffic is being transmitted.My wife's iPhone 4G and my son's iPod Touch wifi both show they are connected to the home network, complete with wifi bars being displayed, and the checkmark is present next to the home network connection in the the device settings for both. When I check the E3000 DHCP clients table, both Apple devices are listed as holding a connection. Yet both devices display network errors when trying to use any app that connects to the internet. By restarting the wifi connection on each, the connection is restored to the point where traffic now transmits. My wife and son estimate it is after about 10 minutes that they encounter the interruptions.
On the PC and NetBook, the connections have to be terminated and reconnected. I have not timed these to see how long before the connection becomes problematic.Interestingly, my ASUS laptop and my iPhone 4G do not have the issue, nor does my work laptop (Dell).There are no timeout parameters in the router config. Closest thing to it is the Beacon Interval, but I don't know which way to adjust it (up or down) to manage the devices that are experiencing interruptions. I have not made any interval adjustments...at this time, everything is set to default settings.This E3000 replaced an aging WRT54 (hardware v2) router so that I could have an N router in the house.

I have att dsl and im using a linksys wireless router and lately my interenet keeps disconnecting. Specifically the little wireless icon in the bottom right of my windows 7 display gets a yellow exclamation mark for about 10-30 seconds then recconects. Its quite annoying and seems to be happening more often now. I have a strange setup on the router, i think its running in bridge mode or something and the modem is doing the actual routing.

I'm trying to set the various computers in my house to static IPs. When I do, the apprear to still be connected to the home network but lose internet connection. I'm using a Medialink wireless router, but I'm trying to set the hard wired lan connections, not anything wirelessI go under ipv4, set:ip address: 192-168.0.100 (or 101, whatever)submask fills in to 255.255.255.0Default Gateway: 192.168.0.1I also went into the router setting and change (dchp?) to only automatically assign from 192.168.0.120 and up so nothing conflicted.

I have a HP G62 laptop and it randomly disconnects from the internet even though it still has full wireless signal. However if I turn the laptop 180 degrees or lift it above my head it will reconnect .The laptop will also only work in certain rooms of the house and not others even though it receives a similar strength signal in all of these rooms. For example it will work in my bedroom which is upstairs and on the opposite side of the house to the router but will not work in the living room (unless i hold it above my head) which is right next to the router.
A second HP laptop in the house has no problems and will remain connected no matter what room it is in and how is held. The two can be right next to each other both with full signal and one will be connected to the internet and the other wont.I have tried updating the drivers on the laptop but this has made no difference. The router is an echolife HG520b. The hp laptop which has the problem has a Broadcom 4313 network adaptor where as the laptop which works fine has a Realtek network adaptor.

I have this problem of loosing internet connection every 1-2 min. I ping Google and I have a lots of Requested timed out about 7-8 of those then I have a reply for 30 sec than it starts again "...timed out"t first I thought it was a problem from my ISP than I called them they checked and it seems that everything it's OK and their behalf. I keep calling them for this problem and they came changed the cable and the router but the problem keeps going.I've had the same ISP for over 2 years now and I didn't have any problem but has started about 1 month ago. At first I was using a TP-LINK 54M Wireless ADSL2+ Modem Router connected throught Poppe with a username. I thought it was that the modem had the problem but the ISP brought a new modem BILLION and the problem keeps going. I've tried in two different PC's same problem.

My desktop is connected to the internet via cable modem, then to my laptop via network bridge between the LAN and wireless NIC, then through to the laptop via wireless ad hoc network.
The problem I'm having is that my laptop loses connectivity every 5 minutes, though it doesn't show a dropped connection. The desktop does not show any connections to the current network at anytime, however I still get connectivity on the laptop albeit only 5 minutes at a time.
I have, on both systems, disabled power saving for the wireless and wired connections; and also that they have the most current drivers.
It does not have to be idle to lose the connection either, I can be in the middle of something when it drops.

I have a 1 month old Samsung 900x laptop with SSD drive running Windows 8 on a home network. I use MS Office 2007 and Explorer.I am now having problems where I occasionally lose the wireless network connection with "limited"superimposed on the connection bar. Another computer on the same wireless router always continues perfectly.I have shut down and restarted the Samsung and this sometimes works. Other times it seems to come back on its own.

I recently bought a iMac and it has been fine apart from the wi-fi connection.It used to disconnect me for 2-4 minutes every now and then at first and then this died down, but recently it keeps losing connection altogether. When I go on run diagnostics it says that i have failed to connect to the ISP and internet.Is there anyway to fix this?,I use a Netgear router with an Apple iMac running with OS X Lion

I have a Netgear DGN2200 router/modem and have been having this problem for a while now. Every so often the internet will cut out for roughly 30-60 seconds. There doesn't seem to be any pattern to the connection losses and they can happen at any time in the day (overall it seems to occur every hour and a half, although it can vary). When the internet connection is lost, the little "!" triangle appears at the bottom right. I still have wireless access to the router itself. It also occurs on both my wired computer and the wireless computer. On the Netgear itself, the internet light will either flash rapidly green, or sometimes turn red for a short while. The Netgear is plugged via a splitter into the telephone socket. the old neatgear we had did the exact same thing before it finally died and no longer worked at all. Hence why we replaced it with this one. I also rang AOL about the problem, who said that there may be a problem with the line and that we should ring BT about it. We had the line checked and apparently the line was fine and was not the cause of the problem. Things I have tried include changing the router channel and I have tried changing the splitter in case that was faulty. Do you think it could be a DSL problem on AOL's end? It's possible that the drops coincided with a free upgrade they gave us for faster internet, although time-wise I'm not entirely sure.

I've been having some problems with my new custom built computer connected wirelessly to my Router. My router is an SMCD3GN. So it is a Router/Modem in one. I am currently using the Linksys AE3000 Wireless-N USB Adapter. I have had a past Wireless USB Adapter, & an internal Wireless network card. The USB quit working & in order for me to get it to work is I have to reinstall the drivers everytime I turn my computer back on. The internal wireless network card would randomly lose internet every 30mins - an hour. Being a gamer, this is very frustrating. So, right now I am using the Linksys USB, and I was just playing a game & talking to some friends on skype & I would lose internet for 2 seconds then it would automatically reconnect. So I am beginning to think that it might be my Router but I tried my USB on my laptop for like 10 mins (I disabled the internal wireless network adapter) & I went into cmd.exe and pinged google for about 10 mins, & it said "Request Timed Out." several times.

I called my internet provider to come fix the problem and my internet was working PERFECTLY. Until, it started to mess up again. I don't know, what's wrong with it AT all. The Linksys box is working fine, the ROUTER is working BUT, my internet keeps dropping and takes HOURS upon HOURS to come back on, UNTIL I reset the Linksys box. Then it stays on for a bit. A few hours or a few minutes then suddenly, "No internet access."

When I am downloading a large file, usually a steam game, the internet connection drops across my whole house, and then comes back up within a minute or two. This is very annoying when i am trying to download a game and do something else. Now this isn't an ISP problem, the internet light is always on for that. But the router seems like it might be the problem. I have a linksys e2000. Is there anything I can do to prevent this annoying intermittent connection during heavy use?
