E4200 router dropping connection

I have e4200 router and i notice sometimes when i am browsing that dops connection.
how would i check this and what should i be looking at to fix this?
Any info would be appreciated.

Changing channels is one of the best ways to resolve intermittent wireless connection through the router and there's really no fix type of channel, they all depend on all devices in your entire network. You may refer to the link provided by jlbjlb about the inSSIDer to help you find a none-overlapping channel or one that is not very commonly used. 5GHz and 2.4GHz are two different wireless frequencies so for as long the other is not on the same range than the other then it should be good.

Router drops connection

Hi, I have a WRT300N that acts as a router/DHCP in a small home network. I have a p2p program, DC++, which requires port forwarding to work correctly. I have setup this in the router, port 1412 and the computer ip address to forward to. The problem is that the router drops connection to internet now and then, with 1-2 hrs. intervals which disconnects all hubs and downloads/uploads in DC++. Very annoying indeed. This has never happened with previous routers including a 3com and a Zyxel, so it has to be something with the WRT300N. What can cause this? I'm not sure what information to send with this message, so it's better if you tell me what you need. Thanks in advance, Mattias Sarling

hi... try upgrading latest firmware on the router, go to www.linksys.com/download and download the latest firmware for the router, after upgrading firmware on the router, reset the router back to factory default settings and reconfigure it according to ISP settings, reduce MTU to 1458, try reducing connection on p2p program... also you can enable QoS to manage bandwidth.

E4200 Constantly Drops Connections (Wired and Wireless)

My E4200 seems to be dropping connections throughout the day. For wireless it'll still show full signal and connection, but there will be no internet activity for about a minute. Then after a minute things will work just fine again.
For wired I notice it in my XBox mainly when I get dropped from games as constant as the wireless drops.
I believe my modem isn't the problem since the old router never dropped connections on the hard wired devices. Occasionally my old D-Link router would drop wireless, but never this frequent
I am running 1.0.02. I've rebooted the router/modem several times. I even reinstalled the entire setup with the current version of Cisco Connect as the tech person suggested, but still no help. The first week or so using this router was flawless, but ever since then it's been dropping connections several times throughout the day to any device connected (wireless or wired). The problem seems that the router just hiccups the connection very quickly, so quickly that Windows doesn't even recognize the connection has been lost, but long enough to drop a multiplayer game on XBox or to have me mashing refresh on my internet browsers.
Does anyone have any ideas?

I have not had this problem with my router and have had it since Feb 2011. I did have a range extender from WNR2000RPT Netgear that I had to reboot everyday and finally threw it away and bought the Linksys RE1000. The combination is flawless in my 3000sqft. house. I will say though it may have to do with your setup and what channels you are on. I have my router setup just for wireless and not as a DHCP server and let my FIOS router handle DHCP. Just so I am not running 2 seperate networks in the house. I also gave my E4200 a static IP as well as the Range Extender static IP. So there would not be IP address conflicts that could cause for possible issues. I did have a problem with the latest firmware disabling my USB for my external hard drive so I had to downgrade to resolve that issue.

WRT160N Router drops connection

I have a couple laptops connected to a brand new WRT160N. Previous to putting in the new router, I never had any problems. Now that I have the new router, one of my laptops keeps dropping the connection. I have to open the wireless settings and disconnect/reconnect to get it to work. Oddly, sometimes when I do that there is no password in the connection information, but if I close it and start it again it generally works. I am using WPA2 encryption and windows XP machines.
Any thoughts?

I have the WRT160N router, running a mixed g/n standard (though both computers connect through g) with WPA2 security. Both laptops are Windows XP, though on the one that loses connection I did upgrade from SP2 to SP3 to see if it made a difference (none). I have a NAS drive attached, but I just put that on last night. Also have an iPod docking station attached (internet radio to my stereo), but have not used it and unplugging did not seem to impact. Other than that, I think its pretty vanilla.
I am not a real tech guy, so if I missed anything important (and I assume I did) let me know.
Any help is appreciated.

Router drops connection when another user joins.

I recently moved and am using a new router and internet setup, everything works fine until my roomate tries to connect, it will immediately drop both me and him and I get a limited access warning when trying to reconnect to the router.
The router in question is a WRT 110 linksys model
it works fine if one of us is logged on and it will work fine if after we get booted I unplug it for about 10 seconds but if one of us is using the internet and the other tries to get access we both get dropped. Scratching my head on this one.
Any help is greatly appreciated

Is it working now? Try to enable MAC cloning and clone your PC's MAC address. That should work.

WRT300N router dropping connection when browsing pages with Adobe Flash 9 content

My router seems to drop my wireless connection frequently when accessing web pages that contain Adobe Flash 9 content? I cannot find any settings or determine if there is anything I can change on the router to affect my performance? I am up on the latest firmware, so that is not the problem? Any help is appreciated.

I have the exact same problem. It's not every flash page ,just some. Power cycling the router gets it back, but it is getting annoying.
Anybody have any ideas?

WRT310N Drops Connection

Hello,
I recently purchased a WRT310N (version 2.0) after using a WRT54GL for years.
Here are my issues with this router:
1. After updating and saving settings the router will drop its IP address and won't renew it without a reset. Connections to the router are fine, but no web access. My WRT54GL doesn't do this, both using the same modem.
2. I am using port forwarding to remote desktop into my PC. I can connect initially for about 5 seconds but then the router drops connections and requires another reset. I have reset the firmware to factory defaults twice and setup nothing but port forwarding. The disconnects still happen.
I require remote desktop to this PC for work so it's crucial we get this functioning ASAP. It doesn't make any difference whether I'm using wired or wireless connections. Issues are the same.

As you upgraded the router's firmware,I would suggest you to reset the router for 45 seconds and reconfigure all the settings again.Reduce the MTU value to 1350 and click on save settings..Under the Security tab..Uncheck Filter Anonymous Internet Requests.Power cycle the router and check..

Dropping Connection with WRT54GS v4

I have had a problem for the last week where my router drops connection intermittently about every 20-30 minutes. Once it drops, I have to unplug the router and modem and start over. It happens over and over again. Hooking up directly to the modem results in a normal, trouble-free connection. I have tried changing the channel, the SSID name and restarting everything sequentially without success. Any ideas on how to fix this would be greatly appreciated.

i started getting this problem, or at least a similar one, lately. i have a WRT54GS v6 with the latest firmware (1.50.9) that randomly decides to stop allowing wireless connections. devices that are already connected will stay connected and be able to access the internet through it, but if you restart a computer or try to connect with other devices, it doesn't find the router.
i have changed the SSID and set it so it does not broadcast the SSID, but that shouldn't cause it to stop accepting connections. i usually only have my laptop and a couple wii's connected to the router (my own and 2 of my roommates).
the only way to fix it when this happens is to unplug the router and plug it back in.

E4200 dropping connections

my e4200 updated with latest 1.00.1 firmware is constantly dropping connections from the outside to existant lan servers running low traffic services when my machine is using torrent or internet gaming.( call of duty modern warfare )
anyone else with that behavior ?
when will cisco fix this ?
cheers

lordgrinz,
I believe you. I just wanted to point out there are many users not experiencing issues (given their needs and the features they use). Given this, there are perhaps specific scenarios / setups under which the issues occur, some of which may not be Cisco's fault (software or hardware conflicts with equipment from other manufacturers).
For example, when I used my Rosewill wireless utlity (came with my 802.11n USB adapter), it conflicted with something that caused the E4200 to stop broadcasting wireless / lock up on the wireless side.
I stopped using the Rosewill utlity and the issue has not happened again in over a week (I reproduced the issue by reenabling the utlity at one point and within two days I experienced the same problem again).
It also did not happen the first few weeks when I was not using the Rosewill utlity and had occurred another time when I used it right after getting the router (i.e. during the 2 periods of time during which the utility was disabled I had zero issues and the two times I turned the utility back on, the problem occurred again.
(I only liked the Rosewill utility for it's advanced view of wireless networks in my area, including their exact signal strength, channel etc. I think SSIDer, as an alternative, provides this anyway).
That is just one example.
I am not saying the E4200 does not have flaws (I believe there are some documented DHCP issues that some have experienced etc.).
I am only saying that with my setup and the features I use, my E4200 has been rock solid.

E4200 - Dropping connection

Save your money...get a cheaper router...because this is NOT worth the extra money...I will most likely have to get an extender...and my router and computer are no more than 50 feet apart, all on one floor, with two very wide archways between the two devices, and I experience drops every day...When I called tech support they tried to tell me that they would exchange it for the 3200!!! That is the cheaper model!!! I told them to send me half of what I paid so that I could buy an extender! Obviously they wouldn't do that!!!

There is no such issue with the router E4200 which creates such kind of problem. Just it requires proper settings on the router’s web interface. So if I relate your issue then the above mentioned solution justifies the troubleshooting steps to be taken, however, in addition to that I would also like to suggest you to try and install your Linksys E4200 router using the Cisco Connect Software just in case, if you are not using it....
Installation disc that came along with your router would help you in installing this router using the Cisco Connect Software, using which you can expect this router to offer you best throughput with wireless connectivity in terms of downloading and uploading of data.....
To set up your router using the Cisco Connect Software, you can use:
http://www6.nohold.net/Cisco2/ukp.aspx?pid=80&app=vw&vw=1&login=1&json=1&docid=e30f926604334d5386685...
Also, try re-installing your router using the Cisco Connect Software, and it should help your cause....Just in case required, you can use the above mentioned troubleshooting steps.....

Amazon Q&A - E4200 - Drops Connections for Wifi Thermostats etc.

Date: Sep 18, 2012 1:01:07 PM PDT
I have issues as well. Drops connections for thermostats (Wifi) and other devices. Range mediocre as well. Will be replacing it. Linksys has gone downhill.

Hi there. Is your E4200 a hardware version 1 or 2? Have you tried to change the wireless channels on the router? If you're trying to connect to the 2.4 ghz band you can try channels 1,3,6,9, or 11. There are external factors that we have to consider when it comes to wireless connectivity - distance, interference with other wireless devices. If you have tried those, you can try to update the firmware of the router which you can find from Cisco's homesupport site (http://homesupport.cisco.com/en-us/support/routers/E4200).

FiOS Quantum Gateway Router - Intermittent Dropped Connections

I just got this router and incredibly disappointed!! I had the Arcotec.. Excuse my spelling and was having intermittent problems with that but this new a Gateway is herendous!!! I can't believe they charge you a 199 for this. Wifi signal lost constantly. Called tech support.. Now they want to charge me 75 bucks for an extender that they say will help.. Optimum looking better all the time!! Very frustrated.

I am experiencing the exact same issue. My issue also started after i upgraded to their 50/50 plan and swapped out my Actiontech M42xxx for the Quantum Gateway Router. They had me do the following and i am still having the issue. 1. disconnect the coaxial cable and the power from the router2. Reset the fios box in my garage by unscrewing the battery power and removing the battery3. Replaced the router (Verizon did this and the replacement was another Quantum Gateway)4. Replaced the box in my garage (Verizon did this)keleko68 wrote:
Hi All, I upgraded my FiOS service a couple of weeks ago to the Quantum 50/50 service and bought the Quantum Gateway/router (model# FiOS-G1100). I used to use the Actiontec router (model# MI424WR, Rev. I). I've been having issues probably for months with intermittent or dropped connections on both wired and wireless connections. Fast forward to the beginning of December. I called tech support enough to the point of them sending a tech out to look at it. My ONT was old, and he replaced it. I had hoped that this was the issue, but it wasn't. The drop-offs continued. I again hoped the upgrade in service and router would also fix the issue. Nope... didn't. This 'latest, most powerful' router only has two lights on it, one for wireless signal and the other that looks like a globe. The router sits on my desk, so I can watch the lights. While I am surfing around, the globe light will suddenly flash for about 5-10 seconds. While this is happening, my connection drops/stops, and then resumes a couple of seconds after the globe light stops blinking. I also noticed that the globe light will turn red once in a while, but not nearly as often as the blinking white does. It's not really consistent as to how long I can be online before the connection starts dropping. I haven't honestly watched it for a long period of time (in other words, I don't know if it's still doing it while I'm not at the computer). I just notice it while I'm trying to use the connection. Once the router starts disconnecting, it can happen as often as every few minutes. VERY annoying. My setup is:2 Mac laptops (one used wirelessly and one used wired connected to a display)1 Apple TV (wired)1 Apple Airport Express (wired)1 printer (wired) I don't have any cordless phones, powerline adapters, wifi extenders, or other electronics that might be messing with the signal. I use VPN software but haven't noticed a difference with it on or off (I think). Any thoughts as to what this might be or where to look? Thanks in advance. I am still having the issue. there is obviously an issue and either Verizon knows about it and doesn't want to say they know there is an issue and fix it, or they are too dumb to take the time to find out. Each time i call i give them detailed information on the issue and ask them to check their knowledgebase if its listed as a know issue and they keep saying it's not. The issue happened again tonight, 1/8/15. at first my laptop dropped Internet connection while i was surfing. then i checked my other wi-fi devices and they all lost connection. i then went and checked my wired devices and they too lost connection. I look at the router and this time both the Globe Internet and the Wi-Fi lights were solid white. i looked at the Internet Ethernet light and the bottom light was green. I could have resolved the issue by unplugging the router and plug it in back, but instead i called Verizon so they could see the issue. 10 minutes into the Verizon call queue the Globe Internet light changed from solid white to solid red. 5 minutes later i finally got to speak to a tech. at first he said the box in my garage wasn't connecting to the router and asked me to disconnect the coaxial cable and the power and, according to him, he sent some command and instructed me to connect the coaxial cable and power the router back on. I did that and then the issue went away.I told him the rootcause of the issue was not identified and fixed and the issue would occur again and i needed him to alert engineering or product development about the issue. i then told him its a know issue with the router and he should do a google with "Verizon Quantum Gateway dropping connection" and he would see how many people are having the same issue. I told him Verizon need to take their heads out their A*%%%$ and spend some time and investigate and resolve the issue. Me

Frequent dropped connection on home router

I have been having this problem for a few weeks now. When I am at home my router drops the wireless connection to my MBP intermittently. Sometimes it is frequent and other times there are several minutes/hours between issues. Occasionally, I even have to reselect my router from the list of wireless networks on the airport menu bar.
I went into the system logs and found this information that may or may not be helpful, but seems related at least.

Just adding my two cents since the thread you reference is sooo long now. Glad I'm not the only one experiencing this.
I was at a hotel this week when I noticed the Airport going four bars, no bars, four bars, no bars. My iPod Touch had no problems at all. I gave up and went to bed (putting my MBP to sleep). In the morning it worked fine.
Now back home; I use a static IP (no DHCP) at home, and started seeing the same thing again. Here's what I see in /var/log/system.log (same thing I saw while on the road):

E4200 Drops connection

Hey guys I'm having a bit of trouble with my e4200,
It keeps on "dropping" connection, and by dropping I mean it constantly around 3-5 minutes the internet stops working with all my computers, it's connected by wifi with 2 PC's, and 1 PC is wired with an ethernet cable, and I also have 2 mobile devices connected at it. The internet would start working again within 30s, to 1m, but that it drops soon.
Methods I've done to fix it:
-Updated firmware to the latest one
-Set the MTU to 1400
-Reset it, (30 second press)
-Rebooted, (Cooled down, doesn't really run hot just a little warm)
-Restored to factore defaults
Please help, thanks!

Hi , have you tried observing the modem's internet connection?
I believe that I can make it

E4200 - Extremely high latency, drops connections

I have 50mb high speed Internet via comcast using a docsys 3 modem, and my wired connection is blazingly fast. I am more than happy to pay for performance, thus this purchase. And that's precisely why it's so infuriating to have 5 to 10 seconds of waiting for a web page to even BEGIN to load via the wireless network. Something is seriously wrong with this router - probably the firmware - even though I'm up to date (I called to double check)
Once connections are made, the transfer is impressive. But I'm not sure the 5+ seconds to start each connection is worth it.

There might be some settings required in the router so that it gets the proper solution. If you are facing the concern of getting lag, dropped connections then you can try the following steps:
A] With the help of Cisco Connect Software (if at all you have installed the router with the help of this software)
1] Open the software and go to the option which says "Router Settings"
2] Then click on the option which says "Advanced Settings" which will take you to the router's configuration page.
3] Lower the MTU (Maximum Transmission Unit) from 1500 to 1400 or less (usually found on your router's main/ basic setup page)
4] Then go to the Wireless tab, keep network mode as mixed,
For Channel Settings of 2.4 GHz you can make Channel Width to 20 MHz only and Channel to 6, 9, 11..
For Channel Settings of 5 GHz you can make Channel Width to 20 MHz only and Channel to 40 or 161...
B] If you haven't installed Cisco Connect then you can log on to the router's user interface using it's default IP address in the browser which is 192.168.1.1 and type in 'admin' as the password leaving the username field blank. This will take you to the router's web interface and then follow steps as mentioned above to make the changes.
You should also make sure you upgrade the drivers for the WLAN card on your laptop computers.
Second, for best results, wireless-N routers should be paired with wireless-N adapters in the same way that wireless-G routers should be paired with wireless-G adapters.
Should there be a mix of wireless-G and wireless-N adapters connecting to the network, it would be best to set the wireless network mode to Mixed. This will allow wireless-G devices to have a stable connection to the network and will allow the wireless-N device to still connect to the network but will be performing based on the wireless-G speed.
