Networking :: D-Link DIR-636L Wireless Drops Periodically
Jun 17, 2013
Just a few days ago, my router started acting up. We have several laptops and phones all connected fine, then I will suddenly lose internet access. The windows 7 networking icon is showing me connected but no internet access, however, I can't even connect to the router ip address over wifi. If I use a wired ethernet connection, then everything still works. If I power cycle the router, then everything will work for an hour or two before it drops the wifi connection again. When the wifi goes down, all computers can see the network, but none can connect to it. From windows 7, it just times out.
What could be causing this problem, and steps can I take to troubleshoot this kind of problem?

I can install things, run CCleaner, and do other basic tasks. I've been stumped about this issue for months and after repeated, and failed, attempts to resolve it via the ISP. I've done searches via Google, this website, and all the other places I can think of, so hopefully I didn't miss a solution to my problem. When playing games online, my internet connection will occasionally drop for 5-8 seconds, every 5-10 minutes. Sometimes, the game will allow me to reconnect after a short lag spike. Other times, I must meet a breakpoint for getting booted, and I'll have to leave the game.

I'm currently writing this from a laptop. It can access the internet perfectly, with no dropouts and no speed issues. However, my desktop PC is a different story. When I purchased the PC, it came with a standard wireless PCI adapter which really wasn't doing the job. It couldn't pick up my router from just one story above, where my laptop could. I decided to buy a new wireless adapter that would hopefully fit the bill. Unfortunately, again it didn't pick up the router from downstairs. Trying a different tack, I purchased the Netgear WRN2000 as an access point that would increase the range of my router. I connected my PC to this after configuring and all was going well for a while, until now. Now, every 1-2 minutes, the internet will slow to a crawl for 30 seconds or so, and while comparing speeds via the laptop (connected directly to the main router) and via the PC (connected through the extender to the router), the laptop clearly has the speed advantage. This is more noticable when playing games on my PC, such as Call of Duty. Every 1 minute or so, the game becomes unplayable due to lag for around 30 seconds, and sometimes this happens constantly. I'm unable to work out if the WRN2000 has a problem, or if it's interference. I actually tried connecting my PC to my laptop via ethernet, and bridging the 2 connections, which seemed to work for a day or so, but now does not. Also, i'd be willing to purchase a new PCI wireless card if anyone has any recommendations for one that has a strong signal range.

Up until now, my wired connection to my modem has been flawless. Recently I have been experiencing periodic connection drops. This is most noticeable when I play multiplayer games. I use Comcast ISP.[CODE]

I have to reset my wireless router multiple times per day. Seems to just be our two laptops that fail to connect periodically, not other devices (iPods/cell phones/Wii). Both laptops have Windows 7. Router was replaced 2 years ago (went from Belkin to D-Link DIR-655) and the D-Link started acting like this a few months ago and is getting worse. I updated firmware on router last week in hopes it would fix it.

As I continue to have various issues with my revision A version of the DIR-825, does an updated firmware is in the works? Or has revision A been DE-supported by Dlink?
I'm still having issues with: Share port printer no longer being recognized/usable until router rebootedLoss/overload of router which causes all clients (wired and wireless) to loss connectivity Router rebooting itself periodically

My DIR-655 drops WiFi connections every few days. All wired connections are fine. Rebooting the router fixes the problem at that time. Cable modem works perfectly fine. [code]
I'm sure I'm missing some devices, but that should give you the general mix of wired/wireless devices that I use. I'm single with visits from my son every other weekend, so network traffic is not that high at my house. I've had this router for a couple years now and didn't use to have this problem. I've been updating the firmware, and I suspect this problem happened after on one those updates. I just don't know which one. Also, I didn't use to have any neighbors with Wireless Routers (that I could detect), but recently there have been 2 who have gotten them. I was hoping this was a problem that D-Link was aware of, but that does not seem to be the case. I would hate to have to go out and buy a new router (not D-Link).

Rev B, recently updated firmware to 2.10NA hoping to resolve the problem.WIFI is disabled.DHCP is disabled (I run a SBS 2008 server, but for testing i static ally assigned IP info on my test PC and disconnected all other systems including the server).Before updating the firmware, the router would hang for a couple minutes and then be OK for some random period, usually more than a few hours. After updating and resetting to factory defaults, I'm now lucky to get ten minutes of service before it hangs. The "globe" light goes out, blinks yellow and then within 20 seconds or so, goes out for good. At that point I can't even connect to the router's admin login page. I either have to power cycle the router OR the cable modem. I have confirmed it's the 655 by reconnecting my old (and I guess more trusty Linksys WRT54G. Same settings, same WAN MAC and WAN IP, no problems after many hours.

Just installed a DIR-615, not impressed so far I have 3 clients, a Windoze 7 laptop, a Kubuntu workstation (wireless N) and a wireless HP printer. When I enable DHCP reservations and reserve the addresses then save settings the router reboots and when I go back in all info is gone and nothing is reserved. I have been having weird disconnection issues - I lose my internet periodically for no apparent reason so I increased the lease time and am trying to reserve addresses.

what I want to do is setup a Tablet for use and share my one Internet connection with it and my desktop. I do not want the desktop and the Tablet networked with each other. there is a Tablet on Newegg: Velocity Micro Cruz Reader R103. the details say it's communication is 802.11b/g Wireless LAN. so I copy and paste that on Newegg and get: D-Link DIR-601 Wireless Broadband Router. not sure if that's what i need or what the configuration would be but I kind of know how to set it up.my question is can I connect a Desktop and a Tablet or any PC device to a router like this with out networking the individual units with each other? just to where it serves as more a splitter. is there any wireless alternatives to only "split" the Internet connection and not network the desktop and Tablet?

I recently changed internet provider and rented a D-Link N 300 Router. On most days everything works well. However on some days the internet connection on my new laptop that has Intel Centrino Wireless-N 130 network adapter get really terrible (usually on Friday and Saturday). At first I thought that the problem was with provider, but now I find out that my old laptop that does not support 802.11n (only 802.11g) has excellent internet connection (at the same time when the new laptop struggles).
How can I troubleshoot what is causing this problem - the laptop network adapter or the router? Is there some setting for network adapter to force using 802.11g?
My laptop is running Windows 7, if that matters.

Within a property without an available adsl line I'm simply trying to network a wireless laptop with a wireless printer. Both devices recognise the router, etc, but problem sending file for printing to the printer. (laptop does not detect printer). Is the lack of an internet connection the issue or simply a configuration issue?

I have recently moved into a new house that has a DIR-615 router. I have noticed with the router that it will drop the wireless connections after roughly 24-48 hours. The SSID will no longer be broadcast, however, the computers that are wired are still connected.I currently have the E3 hardware version, plus 5.10 firmware on the router

I have a wired connection to the router and typically all works fine. I have several Ipods and laptops accessing the router wirelessly with no real problems. As soon as I start playing America's Army (2.8.5) on my desktop (wired) my wireless connections all drop and the kids start yelling to turn the internet back on. When I exit the game all goes back to normal...

I have a new DIR-655: H/W Ver. B1; F/W Ver. 2.00 NA? It is solid as a rock to my wired computers, but the Internet connection (not the wireless signal) to my wireless devices (laptops and smart phones) occasionally drops out for several minutes, many times each day. It is not necessary to reset my router to reconnect; after a while wireless Internet returns on its own. I upgraded from another D-Link router and never had this problem. In my judgment the problem appears to be the router. why the wireless Internet connection might disappear and then reestablish itself?I used an app on my smart phone to select Channel 11. No neighbors have routers close to this channel. My cordless phones are DECT (1.9 MHz). My microwave oven does not cause this dropout.
The DIR-655 wireless settings are pretty standard:
- WPA personal security mode
- WPA mode is Auto (WPA or WPA2)
- Cipher is TKIP and AES
- Group key update interval is 3600 seconds
- 802.11 mode is mixed n and g
When this wireless Internet connection dropout occurs, the router's signal strength does not decrease; the Internet connection just disappears. Time after time I have confirmed that the integrity of the Internet connection remains solid on my wired computers and disappears only from my laptops and smart phones.I have checked the wireless spectrum when the wireless Internet connection disappears. There is no other signal, e.g., no neighbor's router on my channel (11), and the strength remains at 5 bars.

I have a brand new dir-655 of the B1 / 2.00NA version. It seems to keep a connection alive, but the wireless signal will suddenly and randomly disappear from all of my devices. I have reviewed this forum for hours and have made many changes to my settings, but nothing seems to keep the wireless signal from dropping.
Deleted the B mode, made sure the DNS entries were present, stick on one channel, etc. There are no other routers here and all of my phones operate on the 5 Ghz frequencies.
I never, not even once in three years, had this problem with the A version of the same router, but now it's a constant problem at least once a day. Nothing has changed by the router same brand and model but the newer hardware version.
The only remedy I have found is to reboot the router -- my devices will reconnect automatically once the router reboots, but there is no connection discovered once the connection drops regardless of how long the router sits doing its thing.
I've also notices that there are no wireless clients showing under status/wireless...they were there earlier today, but since the latest reboot, gone.

since getting a DIR-655, and I've had random loss of wireless access at least once a day, sometimes 2-3 times a day.While browsing around the settings looking for a way to increase the DHCP lease times I noticed the expiration times were way in the past. Like January 1970 or some such. Then I looked around and saw that date/time for the router was wrong. ("Current Router Time"). So i set up Enable NTP Server (Tools->Time->AUTOMATIC TIME CONFIGURATION).Ever since doing that I haven't had a single loss of wireless connectivity. Rock solid. For weeks now.

DLink 655 Fully Upgraded Firmware Multiple Laptops have the same issue, each has a different O/S from OSX to xp, vista and win 7. As soon as any laptop tries to download files, youtube, even web pages... There is nothing wrong with my wired connection. The thing is, each laptop gets disconnected then almost instantly reconnected. It is very annoying.The only thing I have found to fix it is turning off my wireless security completely. This is unacceptable! I am a computer scientist and in the security field. Ive tried WEP with both key sizes, WPA-Personal is what I originally was using before I started changed settings.

So I have a DIR-655 and my internet connection drops every day. I have replaced the DIR-655 with a linksys just to try it and it works fine. This has happened with more than 1 of these 655''s. Also I have clients calling saying the wireless drops and it will not let them reconnect until I reboot the router. I have updated to the newest firmware with the same issues. I know its not bad cause I have more than 1 655 doing the same thing at a different location as well.

I have a issue, my DIR-615 V.E3 has been working good. I have multiple computers connected and all get between 280 and 300Mbps. But then after a few hours the speeds drop to 130Mbps on all computers. After I reset the router the speed returns to 300Mbps. I have it set up to run on N speed only so g devices are not connecting.

Model: DIR-655
HW Version: A3
Firmware: 1.35EA
One problem with DIR-655.
Drops wireless connection very often. On the taskbar in wireless network center (next to speaker and time) I can find info: Limited Access. Router doesnt drop internet connection but only wireless connection. Sometimes 3-4 times an hour. It's very annoying especially when you upload large files (for example 16-20MB) to your mailbox. It drops connection and we get Limited Access and you can try to upload again and again. Anotner example during VOIP conversations for example on skype it drops and disconnects skype.Firmware was never updated just router was bought with this firmware. We are located in China so its correct.When laptops are connected using LAN cable it works fine but its impossible to keep laptops connected using LAN cables all the time.The problem occurs only when we are connected by wireless.QOS is enabled, WISH is enabled.When QOS and WISH disabled it's same also drops connections on WIFI.

My laptop is having trouble connecting to the internet. Some of the time it is fine, but at other times it will not connect to my home wireless network (or any other open ones I can find) despite the network being in full signal.The only advice offered by the troubleshooter is to reset the wireless router. This does work (but is very irritating to flatmates!) but doesn't prevent the problem recurring. Only my computer has an issue, and sometimes it will manage to connect to the internet by itself, seemingly spontaneously. The laptop is set to connect automatically, and when not working it also does sometimes attempt to connect, (i.e. it says 'connecting') but cuts out again before managing it. The problem can last for a few minutes or several hours.

I've got a problem with the wireless dropping out randomly. It may take a week before it stops or a couple of hours. I originally thought my microwave oven was swamping the signal when we used it so I relocated the router much further away but this hasn't changed anything. I can still log in to the router from a computer on the wired ports and reboot the router. It also thinks the wireless is working but everything looses connection to it. We have 3 laptops and 4 phones that use the wireless and they all cannot connect when it goes down. This is only a new device - less than 6 months?

I upgraded then downgraded from 2.00 to 2.03 back down to 2.00, and whenever I'm doing about 600kB/s+ it resets itself. Drops connection drops wireless, wired, and the globe internet icon goes Lambert/orange. I've reset the router to default and it still does that. What could be the cause?
I've done a lot of changing around, disabling unicast, changing from WPA Auto to WPA2, etc etc, I just changed the router to Netgear WGR614 v7 and it works perfectly fine now.

my E1000 router locks up and I lose Internet connectivity until I unplug the router's power cord, wait for 10 seconds or so, then plug it back in and let it restart. This seems to be triggered (a.) when I land on a web page with intensive graphics, etc., that takes a while to load, or (b.) if I launch a web page really quickly while another one already is up. it doesn't just happen spontaneously when I'm working on the computer. This computer I'm working on is old and slow, which is why as per my earlier inquiry about having to reconfigure the router and network , I'm looking at changing to an up to date and faster model. I just updated to the latest firmware, probably a week or so ago, but the router was doing this before then and still is doing it now.

I have set up this modem correctly as it will occasionally sync and internet will be connected for a short time 5-10 seconds then loses sync.Have asked ISP to check line and they say it is fine. I have upgraded to current firmware but same result.I purchased for wireless N and print server features.Have reverted back to 4+ year old Netgear DG834GV which works perfectly with same cabling, filter etc. ISP suggest connect VG3631 on ADSL 1 but if I need to do that I may as well take it back and buy a cheaper wireless AP.I also set my existing Netgear as modem only and connected to EWAN port of VG3631 and it did the same thing (kept dropping connection), this suggests that it is a VG3631 hardware or software problem (completely separate to DSL/Line issues).

I have a brand new DAP-1522 A1 connected to an 802.11n wireless LAN in bridge mode. Running in the 2.4GHz band with WPK-2 and AES security/encryption.Everything runs fine 99% of the time, but once a day or so the wireless LAN connection on the DAP-1522 drops and then takes about two minutes to re-connect. It re-connects and then everything is fine for a day or so until the next dropped wireless connection episode on the DAP-1522. I know my 802.11n wireless network is 100% fine as during the dropped connection to the DAP-1522 I can connect directly to the 802.11n wireless network (running from my gateway/router) using my other computer, no issues.I've seen some posts on this forum that the A1 version of the DAP-1522 hardware is not 100% compatible with the 802.11n network standard and there will be intermittent wireless drops. If this is true, it's just insane. All I can say is I can't believe DLink would allow a product to be sold that won't work properly on 802.11n networks.I check the logs each time I see the dropped wireless connection and all that shows is the following.1) Negotiating connection 2) 4-way handshake success [mac address]There's no message in the logs about why the wireless connection dropped, but I assume it has something to do with re-newing a key for the wireless network as the successful key renewal messages are the only other messages in the log. When the wireless network dropped I don't see the successful key renewal message at the time I should see it.I thought this DAP-1522 would take 15 minutes to configure in bridge mode and then I'd forget about it. Spend too much time on this already, so a bit disappointed with this DAP-1522 and DLink tech support....though when it's connected to the 802.11n wireless LAN it works fine.

Model : TL-WR741ND
Hardware Version : V4
Firmware Version : 3.16.4 Build 130205 Rel.63090n
ISP : Fibertel
My TL-WR741ND is about 1 year and a half old, it was working fine until about 2 weeks ago. I need to reset it, times between resets is not consistent, meaning, it can take 30 minutes, or 8 hours, but it needs to be reset. Right now, there are 2 wired connections (PS3 and Desktop PC) and 7 wireless (4 cell phones, 2 notebooks and 1 netbook). 1 of the notebooks has static IP, and it also has a VM running, with another static IP. Also some port forwarding simply stopped working (ports 80 and 1180), the rest of the ports work flawlessly, but trying to forward the port 80 and 1180 (to the 2 static ips) won't work. I already upgraded the firmware, and the problem persists, also changed the channel (from 6 to 1, and then from 1 to 11).
Installing dd-wrt/openwrt/gargoyle or anything like that, is not an option. The only reason why I bough t this router, was because I could use dd-wrt, I installed it 1 year and a half ago, and it simply sucked, the wireless bandwidth was non existent, and it was a headache. I installed it again last week, to see if it could be a solution, and I was not even able to save changes in the control panel. I need a real solution, and installing a firmware that works only on chrome is not an option (specially when I use Firefox, and I needed to install chromium just to erase dd-wrt)
