D-Link DIR-655 Causing Internet Slow Downs?
Jun 10, 2011
I have been using my DIR-655 for about 2 weeks now with Road Runner wideband services. Starting yesterday my internet became very slow and I discovered the cause was the router. I tried resetting it to factory settings and things will be fine and run smoothly for about 5-15 minutes but after that it goes back to being extremely slow. My speed tests would go from 10ms (normal) to 250-450ms. Before this issue occurred the Dlink was perfect, had full speeds. I am running a wire Ethernet connection.
I am currently using revB and tried upgrading firmware to 2.01NA which had no effect, but make my internet seemingly go back to normal for the first few minutes then nosedive again.I have also changed my speed/duplex settings in Network Config to 1gbs Full Duplex. I've also disabled QoS, and still no change. Not sure what else to do.
When directly connected to the modem everything seems fine. The modem is also the provided Motorola SBG6580 which I have called Time Warner to set the modem into bridge mode and have the DIR-655 connected to it.

I have recently bought a TP Link wireless usb adapter (TL-WN727N). Initially I had some issues with drivers but solved that and my internet was working perfectly for around 2 days. However recently the internet speed has dropped down to extremely low speed periodically for no apparent reason. I can be downloading something at around 700kBps one moment then only have 100B/s the next. [CODE]

Where I try to download files and they do not download. They only download for a few seconds before not receiving any internet connection. Then after a few minutes they slowly download at only a few KB/s before completely not downloading. I also notice random slowdowns when browsing the internet or whatever I'm doing that uses the internet.

This only started about a week ago and everything was working fine before then. My router is causing my internet to be slow (I know this because it goes at normal speed when I am connected directly to my modem)

decided first of all to connect an old router to the master (but not test) socket together with different cabling & splitter/microfilter - everything starting working almost perfectly (apart from downstream data rate was considerably lower than expected each time I connected - between about 1400 & 1600 Kbps - I have max. 8 Mbps).when I connected back my current router everything continued to be OK (apart from low downstream data rate) - until I would restart the current router and everything went back to very very slow.

I have 2 computers on a network, and 3 devices that use wifi on the same network. Basically when ever computer A is connected, every single computer or device on the network runs extremely slow, if at all. I get anywhere between 1200-2000 ping on pingtest with 2-60% packet loss. Even the speed on the "infected" computer A downloads extremely slow. I'm at a loss for this problem, everything runs slow and its because of the one computer connected to it. I have virus software on this computer, but its not the best so i'm not ruling out malware or viruses right off the bat.
Devices: Blackberry, Iphone, macbook (all wifi)
Computer A
Runs windows xp 32 bit,
amd processor
onboard video
[code].....
The internet modem runs to a router (Dlink dir615) then to a switch (or hub, if you will) and then to the 2 computers. The entire problem is solved by unplugging computer A from the system. But other than that I have no alternative.

I have a Cisco 871w that has been a very great product for many years. I recently switched to Windows 7 x64 on my main machine and now i am having all sorts of issues with it.. I have done a bit of research and found that it appears that it might be the firewall on the SDM that is causing the slowness issues. what does happen is that downloads from known good sites will run really slow. If i hook up my Macbook Pro or my Windows XP laptop i have no issues at all. i have tried Disabling IPv6 as well as SMB2.0 and this has not resulted in a fix at this point.

Basically, my issue stems from the latest Boxee firmware from 2 weeks ago, that since then, its been causing my DIR 655 to reset itself, thereby disabling my whole home internet. It eventually turns back on again after a while, but the process doesn't stop.Basically, my DIR 655 is connected, hard wired to my boxee. I also have a NAS 323 hard wired to my router. I've had this setup on my boxee, reading all my movies/shows from my NAS without any issues for the past 10 months. Then the firmware from 2 weeks ago on the boxee started to cause my router to reset. I thought it was a hardware router failure, so I bought another of the same model to try that out, same thing happened though. When I rolled back my boxee firmware to the previous version, it no longer causes my router to reset.Now, besides me trying to figure out how to correctly block the boxee from updating on the router. Is there anything I can do on the router to tell it to prevent it from letting the boxee forcing it to reset? I'm on High Speed DSL. My internet provider modem is acting as a bridge to my DIR 655. Its been working fine for the past 10 months.
I've also done the following:Ensure DNS IP addresses are being filled in under Setup/Internet/Manual? You can find thse under Status/Device Info/Wan section. Turned off ALL QoS Turned off Advanced DNS Services if you have this option under Setup/Internet/Manual.Turned on DNS Relay under Setup/Networking.Setup DHCP reserved IP addresses for all devices on my router.Ensure devices are set to auto obtain an IP address.I have Set Firewall settings to Endpoint Independent for TCP and UDP..
Basically, I've put my boxee back to my previous firmware, and this doesn't cause my router to reset and disable my internet. But I don't get how/why a firmware update can trigger my router to do this?

I am using virginmedia superhub which is supposed to give me a max of 30mbps. I use it wireless but am often getting fluctuations in speed - sometimes 500kbps upto 20mbps, nothing consistently close over 20mbps or close to 30mbps. I have bought a powerline kit - "develo olan 200 AV Wireless N" which has improved the speed but I still get fluctuations.

For some reason, I have been trying to use QOS for several network related jobs (VPN, streaming). It would seem that when QOS is enabled and the appropriate ports are set which a high priority, the speed of my connection drops to a crawl. When I disable QOS, I'm flying again. I have confirmed ports, and protocol types (TCP or UDP) and nothing seems to work.

I am a new network admin at my company, and I am investigating a problem that is on a network designed by someone no longer here. So, I can't ask why things were set up the way they were. Anyway, here's the issue:
We have 50Mbps WAN connections between locations. The WAN devices are 3750s, but the port plugged into the providers network is a layer 3 port. Config is below for one of the ports: [code]
So, these are Gig ports, but our service provider limits to 50Mbps. When we do a data transfer, we can't exceed about 20Mbps total on the circuit. The data transfers at maximum 15-16Mbps.
I'm not familiar with QoS. I've tried to read more about SRR, but don't understand it well enough to know. Are the QoS settings creating this restriction? Our provider swears that the bandwidth is allocated and its not being choked on their end. I have not taken off the QoS config to test it that way because I'm not 100% sure if its needed and serving some purpose. I don't want to break something in order to fix this.
Is the QoS causing this? Do I need to put a bandwidth statement on the port? Should we be using routers and LLQ?

Two week ago I bought the TD-W8970 ADSL router model. Im using a canon pixma IP4700 printer connected to the router USB print server port and everything is working without any issues if I just look to the router functionalities.
However since that Ive installed TP-LINK USB Printer Controller, my both computers (desktop with windows 7 and laptop with windows 8) are getting very often some BSOD.
I was editing all files automatically generated by windows on this cases and if seems that the cause of this issue is the file TplinkUDSMBus.sys (installed by USB Printer Controller).
To check the impact of this, Ive uninstalled the TP-LINK USB Printer Controller software from my laptop and I dont have any BSOD since 5 days ago. In the desktop Im still have the same issue.
The router print server is a nice functionality and I really want to use it.

I've got a Samsung Epic 4G and whenever I leave the wifi connected on my phone at home, it seems to never go into sleep so the battery drains overnight doing nothing. If I turn off wifi and leave it on the 3G network, battery barely drains at all. Is there something in my router that could be keeping my phone awake when it's connected. I've tested it on a friends wifi network and my phone sleeps just fine, it's only when I'm connected to my DIR-655.

For starters I have a qwest m1000 modem and a netgear router.this morning there was a rather large thundestorm that caused my power to cut out while I was usin my computer.. once I got it back up and running the ethernet light on my modem wasn't liighting up.I reallly have no idea what to do. Everything but the ethernet is working. I can still get to my routers website but that's it, and I don't what to do there once I'm on it.Is it possible the storm messed up the settings? Or killed part of my pc/modem? On my computer the ethernet light next to the jack on the back is yelllow when its threw my rouuter, but when I plug my modem into it directly it doesn't light up at all.

I've recently added a desktop pc to the home's wireless network (using a D-Link DWA-125 Wireless N 150 USB adapter rev.A2) and it used to play nicely with the other devices. After switching out the router to an Actiontec V1000H my computer has begun losing most connectivity when the PS3 is turned on.
The pc still sees the network and there is a little activity there it seems. Everything runs fine when the PS3 is off and in the Wireless Network Connection Status display the speed is usually listed at 65-75 Mbps. But when the PS3 is turned on it reads 6.5 Mbps with the IPv4 connectivity bouncing between "internet" and "limited". Windows' automatic diagnosis is "Cannot communicate with DNS server".
I tried assigning static IP addresses to the pc and ps3 thinking there was a possible IP conflict with the dynamic addresses. Thinking there could be a conflict with ports I read up on port forwarding but my knowledge of networking is limited and I'm not even sure if that is the problem.
There are alot of other devices connected, 2 laptops, 2 iPod touches an iPhone the PS3 and now this old desktop clunker. I figure it's possible that the router is getting overloaded with everything and the PS3 just pushes my computer's bandwidth out the window but I would think that there would be some noticable drop in performance on the other laptops as well, which there hasn't.

I've set up my printer (HP PSC 2410) to the router using TL-WDR3600_V1.0_USB Print Service Client Setup and that part's fine. The USB Printer Controller sees the printer as an "auto-connected printer" and I can select the printer as my default to print to. My problem lies with the fact that every time I try to print something, it causes a BSOD. I'm using Windows 8 and checked to make sure the USB Print Service Client Setup program was compatible with Windows 8 before I attempted anything. The HP PSC 2410 printer is on the Print Server Compatibility list so I don't know why I'm having problems.
The error I get each time I try to print is: SYSTEM_SERVICE_EXCEPTION (TplinkUDSTcpBus.sys). One of the draws of this router was that I could hook up my printer via USB and print wirelessly

Yesterday, my linksys router broke down suddenly. I went to the store and bought a new one, a d-link DIR-615. After plugging it in and setting it up, i tried loading web pages and it worked ok. It wasn't as fast as my linksys router but it was fine. When i tried loading youtube videos, that wasn't the same story. The videos didn't load. It started playing but then stopped after a couple of seconds. When i connected my computer directly to the modem, the videos loaded fast. There seems to be something wrong with the video streaming.

After recently setting up a new computer, my entire network seems to randomly loose internet connection. The interval between connection losses is as short as half an hour but it sometimes goes several hours without dying; the connections is lost for anywhere between 30 seconds and 20 minutes each time it dies.The new computer is running Windows 7 and is using a Roeswill USB wireless adapter, but I have tired it with a wire and the connection still dies. I am disinclined to believe that this is caused by a virus simply because this is a brand new computer that has had only minimal use; to be on the safe side, though, I did do virus scans with multiple programs, however, I did not find anything.When the connection is lost, a yellow exclamation appears on the task bar's internet access icon. If I check my available networks, my network still shows full strength. I have tried disconnecting and reconnecting but nothing happens; I don't get any "failure to connect" type errors nor do I get connection back. I have also tried physically removing the adapter/wire and plugging it back in, but that doesn't do anything either.
I am under the impression that the new Windows 7 computer is doing something to temporarily kill the entire network, but I don't know what.For the record, my modem is an old Motorola and my router is an old Netgear. Both are quite a few years old, but I don't think they are the problem as my internet was fine before I added the new Windows 7 computer. There are wired computers and wireless computers running XP, Vista, and 7 also on the network.

Recently I have noticed my internet get slow. I use a comcast cable internet connection that is directly connected to my dlink DR 655. I use the megapath internet speed test [URL] when testing my internet speed. Have a laptop that is usually on wireless and an XP workstation that is connected to the 655 directly with static IP.
I would be browsing the internet and all the sudden the internet would get really slow. This would happen on both my desktop and the laptop and my speed test on both machines would be around .3 Mbps. When this happens I would go and connect the laptop with the ethernet pot directly to the modem. Of course a reboot of the modem has to occur before a connection can be made so once I do that all the sudden my internet is back up to par (12 Mbps). I go ahead and put my network back to the way it was and it all goes back up to 12 Mbps. I have called comcast several times and they are telling me it my router.
This picture shows a snapshot of some windows from the laptop. The CMD ipconfig on the bottom left shows the laptop network settings when connected directly to the modem. The CMD ipconfig on the upper left is the network settings when connected to the router. The web page on the right shows the WAN network settings when the 655 is connected to the cable modem.
Notice the DNS servers, they are different when the 655 is connected to the modem versus when the laptop is connected to the modem. Could this be part of my problem? I have not seen were I can manually change 655 DNS entries ... is there a way to do this? Or should I not even be worried about it?

I upgraded from Vista 64 bit to Win 7 64bit and one of the first things I've noticed was that youtube videos take forever to load, I use to stream on 720p videos in realtime but now even 360p can struggle to load, 480p videos you have to pause for 30 seconds. Oddly, speedtest indicate my full 15mbps down and 1mbps up, regular downloads go fast but streaming youtube, vimeo, or anykind of videos take a while.
My initial guess was that it has something to do with the Wi-fi PCI card. I have D-Link dwl G-550 and on windows compatibility center it says its not supported. Windows 7 automatically detected and installed its own drivers, it works ok.

I have 2 laptops and 1 desktop all connected to the same router, the 2 laptops are connected via wifi and the desktop PC is currently connected via an Ethernet cable, both laptops run windows 7 while the desktop runs windows XP and more or less every time the desktop is booted after a few minutes of normality connection to the internet is lost and the yellow triangle on windows 7 appears so to fix this I have to go into my routers settings via 192.168.1.1 and reboot which then solves the problem and all machines function as they should including the desktop.

I'm currently subscribed to Comcast's 22/5 Internet service. Internet upload speeds on both wired and wireless are about the same at ~ 5 Mbps. Wireless download speeds range from .5-3 Mbps. Wired or Wireless, I receive LAN speeds of ~32 Mbps or 3-4 MB/s. The noticeable issue is wireless internet download speed. I have tried every configuration possible with my router, updated drivers on devices, firmware and tested everything I could on all PCs, and even used the XBOX 360's media extender network tuning feature as a tool in my investigation to find this bottleneck. All reports point to internet download speed. Again, general LAN and internet upload speeds relatively meet expectations. The wired download speeds are slow at times, but consistently meet expectations.
My current Setup:
Wifi
A4 1.33NA
WPA2 Only - Personal
802.11 Mode : 802.11n only
Channel Width : 40MHz

I`m new here I recently purchased the dir-615. I started configuring with cd but i couldn`t get past the step where it should verify if cables are plugged in , so I did it manually. Some pages won`t load , internet speed is slow ( Both wireless and lan speed ) . I am using a PPPOE connection , I even got my ISP to check my settings, and he said it was alright but it reduces my speed by a lot. Usually I download with 1 MB/s with the router on wi-fi I hardly get 50 kb/s and on lan max is 100 kb/s.

I have an E1550 less than 1 year old. Lately, I have been losing internet on the AT&T modem. I called AT&T but as part of their diagnostics, I have to plug the modem directly into the PC. I have loaded the latest firmware to the E1550.Lose Internet but wireless connectivity to router exists.Internet light on modem is out (modem is connected to router)Unplug modem and leave off plug in, internet light is still out.Unplug router, plug router back in - no internet connection but do have wireless connectivity to router.Take cable from modem to router and plug directly into PC internet light comes on in modem and I have internet from PC.Take cable from PC and plug back into router .I have internet via wireless.What I can't figure out is what could be happening in router that would impact modem internet connection. I have replicated this at least 3 times. Yes, the modem is a bit old, but since plugging it directly into the PC works, I'm thinking it has to be the router and I cannot figure out why unless there's some sort of electrical thing going on in the router.

I've bought a TL-WD841ND and was using it normally.
After I arrived from a trip, the internet speed by wireless and by cable is only 0,5~0,7 Mbps...
My internet connection is 10 Mbps, and if I plug direct on the modem, there comes the real speed (9,7 Mbps), but connecting by the router, the speed is 1/20 of what should be. Before my travel i was using it normal, and no one has changed any configuration.
So i've updated to the last firmware avaliable on the website. So i've rebooted it and the "configuration" LED keeps flashing...
I would like to know if this led flashing is normal: (here is a video that i've done: [URL] and what could be happening. ps: connecting by cable, the internet speed is also the same (even after the factory settings reset)...

I have recently had trouble with my wireless D-link WBR-1310 Router. Two days ago everything was working fine, my wireless connection from the router to my macbook was fine and the wired connection to my desktop pc was also fine. I went to bed and when I woke up the next day everything was still ok. About 3 hours after I had first turned on the PC that next day my wired connection started spiking and dropping connection frequently, maybe every 5-10 minutes or so. I play world of warcraft and I also use Mumble VoiP Program and my pings in both are over 800 constantly now making it impossible to stay connected to either program. Sometimes it will drop down to regular numbers (25-50ms, I play on eastern servers as I am in NY) but then rapidly jumps back up into the 1,000's. My wireless connection is still fine though nothing has happened to that, only my wired connection is messing up.
I've tried changing my speed and duplex settings on my onboard NVIDIA nForce 10/100 Mbps Ethernet which is what im using but it hasn't worked. When connecting directly through the modem the problem seems to stop so its definitely the router.

I have a WiFi in my home, when this laptop is under normal load, say like streaming a 360p youtube video, all the computers in my home will experience a huge lag and it becomes impossible to surf or do any internet activity (even the causing laptop itself will experience huge pings). The weird part is that the lag is at the LAN level, it is not related to my internet bandwidth. Because when I ping my local router (192.168.2.1) with other PCs during the lag period, I get 1000-4000 ms. However, it is usually 1 ms. I tried doing a stress test on one of my normal laptops by downloading at maximum speed, the problem did not occur, there was no lag, all my PCs did not encounter that lag and I still get 1 ms when pinging the router. It is only this laptop that when it starts downloading, my network will be flooded.
Another related problem with the laptop is that every time I log off then log in and try to reconnect to my network, It will not allow me, I will have to click on the windows diagnose problem and it will be fixed saying "Problem with wireless adapter or access point".

I'm using cable (7.5Mbps) w/ unlimited bandwidth . I have 2 wired PC on the network and 4 PCs connected via wireless. My current router is a Netgear WND3400 but I had a Linksys WRT160n v3 previously.
My problem is that I've been getting very high ping in games (PC) and also on my PS3 like > 400ms over the past month but only after like 9:30pm or so. During the day it's always smooth. I called my ISP and they told me everything was fine from their end and the modem too.
1 PC on the network makes the other PCs lag even if that PC isn't downloading or using any bandwidth at all? I did some tests today, like: I open CMD and type: ping -t url... and I get like 6ms but when that particular PC is powered on, the ping increases to > 400ms.

I recently bought a A-Link WNU(m) USB adapter to replace my unnamed unknown wlan thing i had scavenged off an old HP machine. The installation and configuration went fine and windows shows full bars of signal. However, when i ran a speedtest i noticed it was slow as %&/(. The download speed was 0.50Mbps, but on my laptop and with the old Wlan thingie my speed was 7.00 Mbps.
I have tried changing the WLAN channel three times. I have set my wireless to 802.11g only mode, and i have changed the USB port once. The packaging says that the thing has wireless data rate up to 75MB at 20Mhz channel, and 50m range in an office environment. The router is approximately 5 meters from the computer and there is one wall in the way.
Is there something i can do or was my first mistake purchasing a USB Wlan adapter?

I ran a speed test with my new DIR-655 connected to my PS3 and my download is 768kbps and my upload is 1.5mbps. However, my internet connection is 50mbps and 2mbps upload on my computer connected via LAN. While I understand SOME decrease, that's slower than the previous Wireless G router that I had.
I've reset the router twice and it's currently set to the factory defaults. I've even tried setting a static ip address for the PS3 and put it into DMZ mode. However, I'm still getting the slow speeds.
Also, my iPhone 4 is getting about 14mbps download and 2mbps upload. Is that expected?
