Dlink DIR-655 NIC Link Speed
Jan 20, 2011
About 3 or maybe 4 years ago I bought a Dlink DIR-655 wireless router.On the box it listed it as an Xtreme N Gigabit Router, Wireless N (Draft N). I've had two Windows PCs connected to this router by Cat5 with "Intel 82562V-210 10/100 Network Connection" NICs on each set to "Auto detect". The link speed on the NICs show as 100Mbps.Also, I have an MBP and a Windows laptop that connects to this router at times, both with built-in wireless cards.I have Insight Cable and a 20Mbps download and 1.38 upload speeds.This router has worked great for the past years. Since it was getting a little old, I thought I would buy another just like it to have when this one defaults.I ordered a replacement from Amazon. The picture of the router at Amazon was the same as the one I have now.When the router arrived, it was a Dlink DIR-655; however, the router had a different faceplate and larger lights.On the box it listed it as "Xtreme N Gigabit Router". Also listed was N+ 300.
When I set the new DIR-655 up for my LAN and wireless, everything worked OK.However, I noticed the link speed on the NICs had dropped to 10Mbps.I can disable the NIC and then enable, or, unplug and plug in the Cat5 cable, and it will connect at 100Mbps for about 5 seconds and then revert back to 10Mbps.I returned the router to Amazon and purchased another just like it from Office Depot.The same problems are back.I have used the router set-up disk and have done a manual set-up. I cannot get the NICs to connect to the router above 10Mbps.I have turned off wireless, made different settings throughout the router and nothing works.I can set the NICs to 100Mbps full duplex and I get 1.5Mbps download speeds. If I set them to 100 half duplex, I might get 5Mbps.Believe me; I have just about changed every setting on this router with no success. I've turned the firewall, QoS off then on, wireless off and on, put one PC outside the router, but nothing works. Also, firmware is up to date.When I connect my PC direct to Insight modem or connect the original DIR-655, I get 100Mbps on the NIC and 20+Mbps download speed.I cannot get the NICs to connect above 10Mbps on this "new DIR-655" router.

I tested my network throughput speed and it's pitiful. 11Mbit/s or 1450 KB/s! I am running the test from two wireless machines connected via a wireless N router(DLink DIR-655). Both are in good range.I am using the Microsoft NTttcp tool to test my network throughput.

I live in the tampa bay area, I have bright house (BHN) as my service provider, which provides a Road Runner Lightning (40/5) package. I previously used BHN's top tier (20/2) back in July (and prior) with no problems.
After converting to Lightning in August of this year (2010). Of course, BHN (and every other provider) wants to force a modem/router down your throat, so I had them bridge it (in short, turn it into a dummy modem with no routing). I had an SMC branded modem gateway at the time. I work from home 2 days a week (so I can spend more time with my kids during morning, lunch, right after work) and this requires me to use QoS to ensure my VOIP work calls don't get dropped, if the family is watching youtube videos or watching netflex.
My network was as follows SMC Modem >WAN IP>>WAN Port>>D-link DIR-655>>Switch Ports>PC1, PC2, PC3
Everything seemed fine (from a usability stand point) till about 2 weeks ago when my upload speed seemed to grind to halt. Normally I was able to upload about 200-300K per second, and I noticed this dropped to about 45K per second during a drop box upload. First thing I did was power cycle both my modem and router (in the proper/usual order). After they both come up, I start using speed test to find out what my upload speeds were. I was getting about 39Mbps down, but only .56Mbps up still. I factory reset my router.... test, similar speeds. Power cycle all computers (just in case), and then modem/router. Tested, similar speeds. Updated the firmware to the latest. Same issue
Called BHN customer service, they factor reset it, but it wasn't in bridge mode. If I by passed the 655, in factory mode (non bridge mode) upload speeds returned to better than expected states. If I bridged the cable modem, upload speeds seemed to crash.
Had BHN replace the modem, seemed fixed for a day, then issue came back. Had them come back out and replace it again, this time with a Motorolla Surfboard modem... same issue. Fine during factory reset, however after they bridge the modem, upload speeds were fine. Told BHN I would take it from there.. Connected up the DIR-655, and upload speeds crashed again. (.6Mbps). Called D-Link Support, and the Chinese English speaking rep seemed to not be listening to me and tried to have me adjust my MTU as well as Wireless settings. Long story short... the rep was a level 0 id10t and I hope D-link will consider hiring better employees/contractors. So I was all about to give up and replace it with a DD-WRT capable router (which it takes me a lot to want to swap hardware), when I discovered the wan shaping was on. Which I thought to myself... nah... QoS has never messed up before... why would it be the cause. Turned off wan shapping... and voila. Issue seemed to be insta-resolved.
Unsatisfied with that... I decided to dig a lil deeper. I turned on Wan shaping again, but decided to set the settings manually instead of auto detect.
Here are the settings I used... (Advanced Tab>QoS)
Enable Traffic Shaping - Checked
Automatic Uplink Speed - Unchecked
Manual Uplink Speed - 5000
Connection Type: Cable or Other Broadand Network
Enable QoS Engine - Checked Automatic Classification - unchecked (this checked seemed to affect my upload speed by about 5-10% during testing) Dynamic Fragmentation - unchecked (this checked seemed to be the worse enemy for upload speed)
While I know I'm not any network guru (still have to use a subnet calculator for subnetting), I think I did a pretty good job drilling down the issue (once I got passed my service provider replacing modems).
Anyways, I've had overall good luck with D-Link products, even have a 5 port 10/100 switch (all metal) from 1998 that works great. Hopefully, D-Link will just either put more documentation on the web, or hire better employees.

I have been putting up with rubbish wireless signal down one end of my house now for quite some time. So I thought I have a spare wireless router and I could put it down there but I am sure ts not as easy as just plugging it and away you go.
Network Setup
Router 1 is a D-Link DIR-655
Router 2 is a D-Link DI-524
I need to know how to setup Router 2 so it basically become just a wireless access point

when I connect my DIR-655 to the Motorola SB6141 cable modem I notice that the link speed LED on the cable modem never glows blue indicating a gigabit connection, it only glows amber indicating a lower negotiated speed. I am using a Cat6 cable between the two devices and have also tried a Cat5e cable.
When I try and force the WAN port speed to 1000Mpbs in the router interface the cable modem link speed will not light at all with no connectivity. Only resetting to Auto WAN port speed restores functionality albeit at the lower negotiated speed setting.
I'm running the DIR-655 rev B1 at 2.03NA firmware level.
I did connect the modem directly to my PC that uses an Intel Gigabit ethernet card and still had the lower connection indication (Amber) so it seems that the modem might be faulty.

I have a DIR-655 that I have been using for a while (b1 revision). and suddenly I noticed my wifi speed fluctuates constantly. My lenovo Y580 sees speed drop to 130 immediately and then it can slowly progress to 1 Mbps until the hardware is all rebooted. Same happens to my Nexus 7, Dell XPS M1530 and to my roku. I have updated to 2.07 (since 2.10 is advised to avoid). And I have attempted changing channels or factory refresh.What Firmware version is currently loaded? 2.07What region are you located?
What ISP Service do you have? Cable or DSL? Cable (link speed independent of internet speed)What ISP Modem do you have? Stand Alone or built in router? Separate Motorola ((link speed independent of modem)What ISP Modem make and model do you have? Does not matter, router issue.If this modem has a built in router, it's best to bridge the modem. Having 2 routers on the same line can cause connection problems.To tell if the modem is bridged or not, look at the routers web page, Status/Device Info/Wan Section, if there is a 192.168.0.# address in the WAN IP address field, then the modem is not bridged. Not bridged
Turn off all anti virus and firewall programs on PC while testing. 3rd party firewalls are not generally needed when using routers as they are effective on blocking malicious inbound traffic. Independent of issue, not a factor
Turn off all devices accept for one wired PC while testing. Wired works perfect.Check cable between Modem and Router, swap out to be sure. Cat6 is recommended. Wireless issue.

I replaced my old netgear router, which died recently, with a shiny new DIR-655 on my gigabit wired home network. Now I see that file transfer from my NAS is very slow (about 1 megabyte per second). I would like to check if the NAS has connected at 1Gbps to the router. I was browsing the "stat" or "attached device info" in the routers configuration webpage, but could not find it. To be precise, I do see the connection to the NAS, but there is no indication of the connection speed

I've had a DIR-600 for years, and this past month it has been really bad. I have a 3mbps Cable connection, always worked fine and fast, but since the start of the month I've been getting, at most, 60kb/s of download speed (I have a wired connection to the router). Speed tests register everything as fine, except for the download speed, which is really unstable and shoots all over the place, going from 1MB/s to 0 in some instances. I thought it was the ISP being bad since we're having a lot of problems with this provider where I work, but got tired of it and decided to do some troubleshooting myself. When I connect directly to the modem, without the router, I get the same fast speeds I used to. I tried rebooting everything, I tried resetting the router to factory defaults, but nothing seemed to change that. DL speed is always below 60KB/s and if something is downloading at that speed, a single page takes a minute to load.

How can I go about checking the link speed of my wifi on my iPhone? Android devices show it as standard when you click on the network you're connected to and Windows shows it via Task manager/Wireless properties.

I recently picked up this router on clearance to replace a Linksys WRT54GS in the hopes that I would get better speeds for streaming multi-media (NETFLIX). I live in a single story home with a room over the garage (this is where my cable modem and Dlink router are located). To increase signal strength throughout my house I had previously purchased an EnGenius ERB9250 range extender (which supports 802.11N 300mbs), now all my wireless devices show full bars anywhere in the house. Unfortunately when I test my connection to the wireless network I seem to only be registering about 5 - 8 mbs. This really isn't any better than I was getting with my older Linksys, but I thought the Dlink could do up to 150mbs. I have verified that both my range extender and the router are configured correctly, and have tried disabling the QoS (read somewhere that it might drop signals). So far nothing I do seems to increase performance. Is this normal for this router? Am I being unrealistic in trying to get better performance? Is there anything special I need to do to increase performance? I downloaded several wireless sniffers and have set my router to wireless channel 6 as this is the least used by my neighbors (actually shows as 6+2).

ISP is Comcast. The routers hardware version is A4 with firmware v.1.33NA. The upload speed used to be above 4Mbps but recently it has gone down to below 1Mbps. It comes back to above 4Mbps if the router is bypassed or the PC is directly connected to the modem.If I on/off power cycle the router, the speed comes back but only for short period. I tried a new DIR655 of hardware v.B1 with firmware v.2.00 but exact same problem was noticed. I tried my old spare router of Linksys WRT54G and no such problem was noticed.

Router Starts at full speed 300/270/243, jumps around a bit. Then around 5 minutes speed is cut in half 130 Mbps. I tested it out for 2 hours rebooting it, and in almost exactly 5 minutes the speed is cut in half every time. Is my router bad? Or is the good neighbor policy just going into effect? I do have a lot of traffic, I am in a apartment, but I use a free channel

i recently bought the dir-615, and i have 4 computers connected to it, 2 desktops with ethernet cables and 2 laptops with wifi. I want to know how to limit the internet speed on some computers, because i sometimes need full speed on my desktop. Is it possible within the router configuration interface?

I have been using a D-Link DIR-600 for a couple of years now. And I haven't had any problems until maybe a couple of months ago. It all started with my internet just kind of dying (mostly in the eavnings) and not working until i rebooted the router. So I call my internet provider and they tell me to update firmware and to plug the internet straight into my computer instead to rule out everything at their end.After some time I manage to update firmware. Problem with internet sill remain but is not as frequent. I left it like that for a couple of weeks, but earlier this week i checked my connection speed and it says i have only 50mb/s after the firmware update. Since i had the weekend off I plugged the internet straight into my computer and get my full internet speed at about 90mb/s. After plugging in the router again I only get around 50 again.

I have my DIR-655 router set up on the first floor because my son's tricked out gaming rig is in the basement while our office is on the 2nd floor. On the router, I tweaked settings to give him priority speed when he is gaming. Although he complains about his speeds and connectivity. In our 2nd floor office -- which is one floor and 30 ft through a wall away -- my signal strength varies from 45% to 70%. There are times when neighbor's networks show greater strength than mine does. I live in a house so the physical distance is much greater plus there are two exterior walls, no matter where their router is placed. The adapter in the office computer is a D-Link DWA-556.

I just bought this router. Unfortunately I'm losing close to 3mpbs !
When I was connected directly to the modem i had a little over 12.5 Mbps
Now I'm stuck at 9.5mbps and it won't go higher!
I read a bit over the forum. I tried turning off the QOS but it didn't change a thing.
Here a little extra information;
My internet provider is Cogeco
MY computer is wired
I tried 2 internet tester, both give me the exact same result

My DIR655 is A4 with firmware v.135.
My normal uplink speed is above 4 Mbps but the speed goes down to 0.4 to 0.8 Mbps. The above unit was received from D-Link as a replacement for the same reason, but it worked for at lease 12 hours.
If the power is OFF/ON cycled, the normal speed comes back but last only about 10 minutes.

I get from my ISP 50 Mbps upload/download link via BGP. I tried to test today the speed by downloading around 10 torrents simultaneously and I use PRTG Network Monitoring to view port traffic speed. According to PRTG Reports the maximum rate of speed I get is 20 Mbps. I use Cisco 2821 ISR on my side.

I've got a Buffalo LS-WXL5BF connected directly to one of my PC's gigabit ethernet ports. The link in the Win7 network and connections is showing it connected at 1Gbit but the actual transfer speed tops out around 150-200 Mbit or roughly 15-25MB/s (which is well under what the unit is advertised to perform at.)
I'll be swapping out the cable that came with it for a good CAT5E I got from monoprice but other than that I'm not sure what to try.

I bought my d-link 615 a few days ago and managed to connect it to my network and so on but I have a problem when it comes to my download speed. My usual speed is somewhere between 7.5-8 mb/s but when I have the router installed it's limited to 5 mb/s. Do you know why this might be happening?

So I'm on the 100mbps virgin fibre optic broadband, and for the past couple of days, every now and again my speed drops drastically. It's not the Internet, because I've tested it on my laptop both wireless and plugged in. Even my phone and iPad are getting higher speed.
When I first got the internet(About a week ago) my download speed was 100+ mbps, but now my Link speed is constantly at 10mbps, even if I set my NIC to 1gbps full duplex, I've tried disabling and re enabling, I've tried uninstalling and reinstalling drivers, updating drivers. Restarting the router, starting it in Modem mode.

Just bought a new DIR-655 Xtreme N Gigabit Router 3 days ago. Have 5MB fiber and consistently receive 4.7-5.0MB when connected directly to my laptop (windows XP, Dell wireless 1390 WLAN Mini-card, 802.11g only). I followed the CD instruction to set up the router and when connected wirelessly I consistently get 2.4 - 2.7 MB. When I connect a cable from the router to my laptop, I get the 4.7 - 5.0MB that I get when connected directly. I've tried a second laptop (Vista, 802.11g only) and when connected wirelessly I get 4.7-5.0 MB. A friend of mine who has a laptop (Windows 7, g/n) also connected at 4.7-5.0 MB.

I previously owned a Linksys WRT54G V.8 wireless router, I upgraded my router to a DLink DIR-655 N Router in hopes to improve my internet download speeds. As a comparison I ran several online speed test for both routers. However, All test yielded similar results with minimal improvements. I also downloaded large files utilizing rapidshare's download manager, again with no improvement in download speed. I thought moving from a G to an N router would improve my download speeds. The drivers on the DLink router are current. Are there any tweaks or tricks i can do to increase my download speeds?

Is it possable to limit the download/upload speeds of a wireless computer on this router, the reason is i am at home working on files from my office computer and my son gets home, and starts downloading massive amounts of music an other ****, and i get disconnected to the office computer, and have to start from scratch again. I just want to limit his speed to maybe 25% of the max internet connection.

I use the dlink router with 12mbits internet connection. Connection with LAN wire, i get the whole 12 mbits. Via Wlan, even while standing next to the router, i only get 5-6 mbits.
I read this can be cos i send in mixed mode b/g. Is that true? How can I set to g only? I only can select "n only", "b/g mixed" and "b/g/n mixed". But I think all my devices use g.

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?
