D-Link DIR-615 :: Starts To Drop Connections Occasionally
Apr 20, 2011
I had a D-link DSL-G604T router which recently had begun to drop connections, so I decided it was time for an upgrade. I bought a D-link DIR-615 and followed the instructions on the CD, but no internet connection. After several hours of hair pulling I came accross a solution; If I connected the internet port on the DIR-615 to one of the ethernet ports on the DSL-G604T using an ethernet cable I could then connect to the internet.However this defeats the point of having a new router if I have to use the old one to connect to the internet.Is there a way to configure the DIR-615 so that is works properly?

I recently upgraded my network because my DIR-655 started to drop connections. My new routers (a Netgear ProSafe VPN Firewall SRXN3205) is working great, but I'd like to re-purpose my D-Link as a wireless bridge.
According to Netgear support, I need to link my DIR-655 to another access point connected to the network over wired Ethernet. No problem there; I have a DAP-1522 connected via Ethernet on the floor directly below the location of the DIR-655. I was under the impression that although the signal was going through the floor, the physical distance to between the two devices would be sufficient to make the connection. No joy. I use the push-to-connect buttons on the two devices, but they do not connect. Is the floor the only issue? I do have an ANT-24 antenna extension for the DIR-655 router -- would that make any difference. As I say, the physical distance between the two devices is less than 10 feet.

I had a Linksys Wireless-G router for a long time and had very good luck with it. However, I ended up getting a couple of Wireless-N devices and wanted to get a different router. I bought the Linksys E3000. I got it home and set it up, and at first it worked. Then it would all of a sudden drop everything connected to it. I would restart the router, and in short order it would drop all connections again. This completely baffled me for awhile, until I actually touched the bottom of the router, and it was quite hot. I had it laying flat on a a table, so I could never understand why it was getting so hot. Anyway...I stood it up on it's side and it worked for awhile. Then it would randomly drop various things connected to it. The last straw was when I was listening to internet on the Apple TV, while viewing the internet on my PC and it started dropping the connection every five minutes. Anyway, I have now hooked my Wireless-G Linksys back up and it is working great.
is Wireless-N even needed? I live in a small place, so I don't need it to reach a long distance, and I don't transfer a tremendous amount of date wirelessly, so that doesn't really matter. Should I even try to fix this router? I looked on the Linksys page and I am running the newest firmware.

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.

webpage A will take 1 second to load, and webpage B will take 6 seconds to load. After a browser refresh, webpage A might take 5-8 seconds to load, and webpage B will take 1 second to load.
Hardware rev A1 Firmware 1.13NA
Router is about 2 years old.
I tried resetting the router prior to the firmware update, no different. This is happening on both PC's. I tried a direct connect to the modem, and it seemed to work fine, but this doesn't always happen.

I started having connectivity issues between my core 4506E (Sup7E) and Cisco 2960S. There were input and CRC errors on Te int (SFP 10Gb - LRM) on 2960S, which cause the interface to reset and drop connections. While troubleshooting this issue, I have replaced patch cords and also had the tech checking the fiber. He said that there was some residue on one of the connectors, so the light levels fluctuated in 1300nm, but worked fine in 850. Well LRMs are using 1300, so he re-polished the tips, which worked to stabilize the light levels. After all that, I was still receiving the input/CRC errors, but the connection was NOT dropping. As my last resort I swapped the SFPs between the core and 2960, thinking I should start having issues on the core end. Well, here's what happened: I stopped receiving input/CRC errors on 2960 (also no errors on the core), but 2960s started generating Rx power high alarms: [code]

I'm using a dlink network adapter (6 months old) on my pc, have always gotten an excellent signal. Main pc in house is hooked up to dir-615 router & works fine. I had some bsod's recently & decided to reformat xp. Loaded the driver for the adapter, got an excellent signal, but couldn't access the net. The signal shows 4 green bars for about 20 seconds, then all white bars for a few seconds, then back to green. It keeps dropping the signal over & over. The network card shows its working properly.
I did an ipconfig, and it says "media state disconnected" & shows no addresses. If the dlink adapter is faulty then i'm assuming it wouldn't work in the first place. I'm thinking its some setting not right in the pc. The reformat went fine, loaded all the drivers in the right order. I only have IE for a browser which i need to access the net with to load firefox & all other programs plus service pack 3 & other xp updates back on with.
When I loaded the driver for the dlink adapter, i used a different workgroup/name than the network name originally used to set up the dlink router if that means anything. I've read about resetting the winsock which i'm going to try, but I would think that wouldn't be it since i just reformatted the pc.

I just recently setup a network in my home and selected the D-Link DIR-655 router to manage traffic. It's not clear to me when this issue first appeared as I've been away so apologies for not having a proper timeline.The router is setup in it's default configuration with only the IP Address being changed due to a conflict with my DSL modem. I don't have any experience with routers and it seemed to be working fine so I didn't mess with it.However, the router goes into what appears to be an endless series of reboots making it completely unusable. This can occur anywhere from immediately upon a cold start power to a few hours into it.I suspected a defective router and since I had been traveling the warranty was of no use so I purchased a brand new router last week which is also a DIR-655. The new router is doing exactly the same thing as the original one.
If I disable the wireless functionality both routers perform flawlessly for extended periods (many days/weeks). As soon as I enable wireless what appears to be warm start reboots begin as mentioned anywhere from immediately to a few hours along.Since I am new to networking in general and routers in particular I thought perhaps am I doing something wrong and hence my post here.The f/w in the new router is 204NA. I don't recall the f/w release of the initial router but I did update it within the last month to whatever was the most current from D-Link. If it's important to know the f/w release of the initial router I will find it for you.
Two (2) DIR 655 routers appear to enter a state of perpetual warm start reboots whenever wireless functionality is enabled. This begins anywhere from immediately to a few hours after a router cold start.Disabling the wireless functionality completely stabilizes both routers.

I having a basic query in troubleshooting E1 link , here im facing packet drop in the link and we are testing by providing local loop and remote loop from the CSU/DSU at local point and at remote point . I have tried ping test while the loop is given at local point and remote point ie i have pinged my local serial interface IP address (eg 10.0.0.1 -local & 10.0.0.2 -remote ) in Remote Loop i could see no errors and drops and also the traffic on the interface output and input is the same(eg input rate 1000bps and output rate 1000bps) .My query is that when i am pinging the local interface IP does the icmp packet travels till the loop point and comes to the same interface(like a boomerang) .
ICMP packet

I have used DIR-655 (HW:B1 FIRM: 2.00NA) with Motorola SB6120 for sometime without any incidents. My dl speed usually is around 26mbps. Lately, it happens twice that the dl speed drop to 10mbps. If I connect the SB6120 directly to my PC, the dl speed is 30mbps. Is my DIR-655 dead?

My requirment is to drop the Internet traffic once the Cisco HWIC 3G backup link will become active(attached) .Because I should allow only Business Critical Data allow through that and others should drop. Here are the config I used. In here I used a standard access list to generate intersting traffic which allow all the traffic traverse through the backup link.Can I drop the packets to the proxy (192.168.1.100) using this access list and allow other traffic.access-list 1 deny 192.168.1.100access-list 1 permit anydialer-list 1 protocol ip list 1.Is this the proper way I should follow ? Is there any other good method to achieve my requirement ? [code]

We have an 877 router which usually runs fine, except that twice in the last few months it has defaulted its configuration!
I can't see any obvious faults with the unit, I can reconfigure it and do a write mem and it will hold the configuration through reboot cycles. Config register is 0x2102 as it should be.

I have 3 WLC 4402 controller connected to an ACS Server and Cisco 1252G AP. Previously the wireless networks works fine but for two weeks now most of the clients experiencing reauthentication frequently, Some experience it every 5 mins even if they are browsing or idle and not moving. I've check the session time out settings in the wlc and it was configured for 30 mins as default. I have around 900 student clients connecting every day.

ACS had been integrated with Active Directory before ACS upgrade to 5.3. After the ACS 5.3 upgrade users aren’t able to login to AAA devices occasionally. Error message is:
{AuthenticationResult=Error; Type=Authentication; Authen-Reply-Status=Error; }
24429 Could not establish connection with Active Directory
At the same time, when this issue occurs, ACS connection to AD works fine (checked with Users and Identity Stores> External Identity Stores > Active Directory “Test Connection”)

The 2 routers are Di-524UP and Dir-655.I have 2 routers and 2 modems,Computer 1 and and 2 are running on the same router as they have low internet usage.Computer usually does large amount of downloading and streaming and requires a separate connection as not to lag the browsing for computer 1 and 2.How could I link router 1 and 2 together so that my computer 3 could deposit files that are downloaded over the internet through wireless lan into my NAS.Or are there any devices that can bridge 2 routers with 2 different network connections over the same lan network.

I have a the aforementioned router set up with one PC laptop connected via ethernet cable and two to five other devices (PC laptops, iPhone, iPad, Linux Laptop) connected at any given time. About once or twice a week the router drops the network. I can still see the SSID, but can't connect on any device. The wired laptop gets dropped as well. I tried to ping its IP, but it says the device is unreachable. The only solution is to walk upstairs and unplug the router, which fixes it every time until a few days later when it happens again. I've restored factory settings a number of times.

I bought a new E1200 this fall when I got a new Internet provider who recommended it to replace my really old one. It worked fine until a month or so ago when it would occasionally disconnect. At first I thought it was my Internet company but I started using the Cisco Connect app to fix it after restarting the router. The first time it worked great for about 2 weeks, but a few days ago it started disconnecting several times a day. Now it doesn't last 10 minutes before it quits. It tells me the firmware is up to date

I have 2 computers hooked up to the router via wire and wife using wireless on her laptop.I'm playing games on internet and soon I noticed I got occasionally ping spikes.. The ping get beyond 1000 - 1500 so the screen is in fact temporary freezed. Sometimes those spikes can occur with 10-15 minutes inbetween them sometimes it can be an hour or more before I notice it.I'm running Windows 7 on both my computers. I first thought it was Microsoft was to throttle the packets so I did the change in the registry. But these spikes still happen. After some testings I also notice they happen at the same time on both computers so my conclusion is that it's something with the router.

I have some issues with win 7 64 bit pro. I have 3 computers on a cat 5 wired home LAN using a DGL-4500 router and in yhe same homegroup. All are gigabit capable. 2 are regular PCs, one is an HTPC. All have the latest drivers.1) File transfers never exceed 12% of the network capacity.2) If I transfer from computer A to computer B's public folder, I can transfer 1GB in a few minutes. However, if I attempt to copy/paste a file from Computer B's public folder to computer A, computer A takes forever "discovering" the file, then gives some absurd transfer time, say 11 hours for the same file.3) If however I go to computer B and paste the same file into Computer A's public folder, the transfer takes only a few minutes.
4) If at any point during scenario #2 I right-click B's public folder from A during a transfer, I get the spinning circle forever which 90% of the time results in Explorer hanging and requiring the process to be killed/restarted.

I have an E2500 router. When I enter 192.168.1.1 as a web address I am asked for a User name and password. When I do not enter anything for user name and put “admin” in password the screen again asks me for the same two things and eventually goes to a 401 message.
When I enter admin in user name and my secure password to allow devises to connect to the network it lets me in. I thought the password to enter the system settings and the one to enter the network are usually separate. When I open the Cisco Connect program and go into the various menus there my “secure” password is written and visible for anyone who clicks it. Is this how it is supposed to work?Also, how do I occasionally change the password to enter into the network.

When my Toshiba Satellite notebook first begins booting up, the ethernet cable "connected indicator" light is ON, but somewhere around the halfway booted-up point, the light goes out. Once booting is completed, I get the message "Network cable is unplugged". The cable is definitely plugged in, as I also have Ubuntu Linux running on this same machine (dual-boot), and use this cabled-connection ALL THE TIME (for both LAN and Internet access)

I would be surfing the internet for about 30 minutes, then all of a sudden the wireless connection just stops. The wireless icon says that I'm connected with an 'excellent' connection, but I can't browse any webpages and nothing loads.
After about another 30 minutes of no connection, the wireless starts again and everything is fine. I tried updating the driver, but it says that it's already up to date. I also did a diagnostics, and I get this message: "Dell Wireless 1490 Dual Band WLAN Mini Card (Failed)".

I have a Westell VersaLink Model 327W router that is linked to two desktops, one with Windows 7 and one with XP. Our internet speed was recently increased, and ever since that happened the connection cuts out randomly and sometimes when the phone rings. After noticing the link to phone calls, I tested the connection by calling the phone to see if I could replicate the problem. However, the internet did not disconnect when I called the phone myself. On the Windows 7 desktop, the taskbar says no internet access when the connection disconnects. Strangely, Windows 7's default Troubleshoot Problems restores the connection every time. The disconnects are still extremely frustrating because they cause me to lose any online game I am playing at the time. I am not completely sure about the symptoms on the XP computer because it is not mine and I am rarely on it; however, I believe it normally reconnects after a few minutes on its own. We also have laptops that are connected wirelessly to our network. I have noticed that they tend to also lose internet access, although the taskbar does not indicate any problems. I am reluctant to believe that the problem lies in my router or ISP because the disconnects began when our internet was upgraded. I have searched the internet for fixes, but so far I have found nothing.

I have a RV042:Firmware Version : v4.0.0.07-tm (Aug 19 2010 19:19:50)PID VID : RV042 V03 .Configured with a internal LAN address (10.0.17.0/24) and ISP PPPoE External address on WAN1.I´ve configured a VPN with a remote location (Fortigate 4) and after the VPN starts up the RV042 cannot ping any machine in their local network (using the diagnostic, all pings failed in 10.0.17.0/24) and no machines in that network can PING and access or manage the RV042
The only way to manage the RV042 after VPN starts UP is using a machine in the other side of the VPN (The Main office)If i force the VPN down, the connectivity begins to work, but as soon the VPN starts up again, the local/LAN connectivity loses again.

I have a school with 550 iPads. We are using two 5508 WLCs sharing the number of APs. The DHCP server and the default gateway for the network are on the firewall. The clients are able to get a DCHP. After some time, maybe about longer than a month, the clients are no longer able to get DCHP addresses. A reboot of both controllers takes care of this. Presently we are runing 7.2.110 OS. I am going to upgrade to the latest 7.4.100, and reload tonight.

I am having trouble with my Cisco SG300 switch big time. I have two servers with IP addresses 10.17.0.11 and 10.17.0.29 sitting on the same switch which is a Cisco SG300. I initiate a file transfer from 10.17.0.11 to 10.17.0.29. I could see lots of Dup Acks and retransmissions which means something is wrong in the connection. Further, I could see the session initiation a bit bizarre. I could see two SYN packets sent from 10.17.0.11 to 10.17.0.29 and also two SYN ACK packets returned by 10.17.0.29. The switch forms part of a network but since both the servers are sitting on the same switch I suppose the rest of the network doesn't come into play when one server talks to the other.
See also the number of Dup Acks and retransmissions. The two switch ports connecting the servers have speed and duplex set to auto negotiate, flow control is enabled. What could cause this sort of problem?Could it be any setting on the switch or the servers' NICs?Or could it be a bad switch that causes this?
