D-Link DIR-655 :: Poor Performance / Mostly Windows Computers
Feb 5, 2012
I replaced a Dir-655 at a coffee shop, with a new dir-655 a few weeks ago. They keep calling and saying that Windows clients are not working and that Mac clients do.My first thought is that they are overloading the router but I would think that all computers would have problems not just the Windows computers. could the router be so bogged down that it takes to long for DHCP request for windows computers assigning the IP twice?

A few days ago I received my DIR-655 I ordered off Amazon and hooked it up. There were no problems the first day after initial setup. The next day I noticed that I was losing internet connection even though the wifi indicator on my laptop said otherwise. This happens for about 5 minutes at a time and on other devices such as my desktop and my iPad. And I hopped on Call of Duty last night and played a competition with some friends and gave everyone 4bar connection. Later that night, I was playing some more and people that connected to me received 1bar connection and I got that in return on their connection. I feel that the router isn't working with my devices right?

I run my virgin broadband through an old NTL modem and a Belkin router. I haveit all attached to a computer in my study along with a new 6TB Buffalo Nas drive. The computer has GIGABIT LAN. I use Belkin powerline units to relay the network around the house. In my lounge i have a blu ray player, AV amp and my sky box attached to the network via the Belkin powerline units and all run ok. This week i have added a Cambridge audio streamer but i am suffering now from a lot of dropouts and network failures escpecially when trying to stream music from my NAS. all seem to be set up correctly as per the manuals. I have spent a lot on this unit specificallly to stream my music so this is really important to get working correctly The powerline units can flash blue (fast ) or orange (slower) but i only see the orange light .My local dealer says i need to upgrade my Modem/Router and has suggested an ASUS RT-N66U which I understand is a modern 2.5/5ghz model . he says my system is overloaded
A few questions.
Is this a suitable modem for me to use on my Virgin cable broadband? (apparently there are two alternatives types of modem/router)
Is there a better alternative unit ?
Could there be another cause for my problems and if so how do i diagnose them ?

having a very strange problem with a Cisco 1861 running - Cisco IOS Software, C1861 Software (C1861-ADVENTERPRISEK9-M), Version 12.4(24)T5
The issue -I have suddenly started to get performance issues with downloads and access through the ZBF. Without the firewall enabled and just having NAT enabled and routing , downloads perform as expected - ( have been using Itunes download as test file ) - with the ZBF enabled , and the necessary rules installed to inspect & allow traffic - downloads stall - and the only way to get the downlaod to start again is to pause , then resume. The stalls are anything between the first 25 - 120 secs.
I have debugged and performed packet traces - but cant see anything untoward. I have also placed another router ( just a cheap Belkin ) on the ADSL service and again , the downloads work as expected.
one further thing to add is that when im tunneling through the firewall ( VPN ) , then downloads do work as expected - suggesting that the issue is with native HTTP(s) traffic.
I have upgraded from T4 to T5 - and the symptons still remain - I am thinking that these may have been introduced when i upgraded to T4 a few monthes ago.

I recently purchased an EA4500. It started out working really well, but recently I noticed that my speed on my iPhone and iPad has dropped significantly. When I'm in my office where the router is set up, I'm getting around 15 to 20 mb download speed and 5+ upload speed. When I go to my living room about 40 feet away my speed drops to 1mb down and less than 1 up. I expect to see a drop in my performance the further away I get from the router, but this seems really unacceptable to me.

The wireless connection barely registers in the Speed Test within Cisco Connect - .56 download, 5.35 upload. A cable connection gives 2.4 download and 5.5 upload. The E900 is not far from the computer with no obstacles between.Is the wireless portion of the E900 set up improperly? Is there anything I can do to improve the wireless performance?

We use MS RRAS services behind a Cisco ASA 5520. In testing the performance I have found that we can only get a little over 2MB of througput when connected to the VPN server over a broadband connection. I have verified that the issue is not the RRAS server itself as I can connect to VPN from the LAN and the througput tests at 300-400MB. I also connected to the LAN directly on the outside of the firewall and only get 4 or 5 MB from there which does not seem right. None of the switches are showing any errors. I believe that I have the passthrough stuff setup as I should. I even went through these steps as recommended by Cisco.
hostname(config)# class-map pptp-port
hostname(config-cmap)# match port tcp eq 1723

hostname(config-pmap)# class pptp-port
hostname(config-pmap-c)# inspect pptp

I have a Catalyst 4006 with Supervisor II engine. I have 48 port 10/100/1000 blades installed in it for connection to my servers. I am having a lot of problems with performance when connecting servers that are using 100 MB NICs. The speed of the connection is really bad. I have attempted setting the ports and NICs to 100MB Full duplex instead of auto-detect, but still get the same results.
I also have a 10/100 quad-port card installed in a NetApp filer. All four ports are trunked together and connect to 4 ports in the Catalyst. The ports in the Catalyst are trunked using the Port Channel feature of the CatOS. When I look at the port statistics on 3 of the 4 ports from the quad-card, there are a ton of runts and errors (both transmit and receive). The 4th port is fine, no errors.

I have 2 RV042 routers with identical firmware (1.3.13.02-tm) and settings. One router is a backup that sits in a box, but both experience this problem. The WAN port gives very poor performance most of the time. Download speeds range from normal, 25mb, to less than .5mb. Pings from my command prompt or the routers "Diagnostic" page, even to the cable modem, are almost always above 500ms. However, pings to internal resources are fast, usually under 5ms. If I connect my laptop directly to the cable modem I have no speed issues. The problem occurs whether I use WAN1 or WAN2.
If I restart the router, speeds are fine for a few seconds and then it begins to slow down like someone is turning down a dial. We also regularly experience a complete internet disconnect quite often, and when it happens, the ping results are the same when it comes back up, almost like the router is restarting itself. [code]

We have two Cisco AP541N running our wireless network in the office. They're configured with the same SSID, so that people are automatically switched between the two access points depending on their location in the office.
Frequently we are experiencing very poor performance of our wireless connections and it seems to be related to when 4-5 clients are connected to one access point. After restarting it (which also moves the 5 clients to the other access point), the performance problem goes away for a while.
I've upgraded one to firmware version AP541N-K9-2.0(1) (the other is running AP541N-K9-1.8(0)), but it doesn't seem to work.

I have EA4500 acting as a router on domainless all-Windows network of two XP machines.Unfortunately, EA4500 aggressively grabs the role of the Master Browser (I am talking about Computer Browser Service) on the network (regardless in which order you power the devices up) and then doesn't serve as a working Master Browser - both Windows machines stop listing the network computers in the "Network Neighborhood" and incur massive timeouts when attempting to view the listing.A quick look with 'browstat.exe status' reveals that indeed the router has announced itself as a Master Browser device, but returns errors when you query it.Quite predictably, without the router, both machinces figure out amongst each other who will be the Master Browser and everything works fine. The problems begin only when you add the router to the network.
1) Is there any way to make EA4500 work like a full-blown Master Browser (the one that not only announces itself, but also serves as such)? having a Master Browser integrated in "always-on" router would really improve the predictability of the network.
2) If not, is there any way to disable the Master Browser on EA4500? For now I managed to achieve that by assigning the router to different workgroup name, but this is lame, as I now can't connect a disk storage to the router and use it within the same workgroup.

We have recently purchased some Cisco 3750x switches and we are getting complaints from users that the performance is poor when both the PC's NIC and switch port are fixed at 100/Full?
There are no errors or collisions on the switch interfaces so there is no obvious problem on the switch. The PC's are standard DELL Optiplex 755/760's
or gx 520's.
Any performance issues when configuring the switchport to 100/FULL?

We have a remote site connected to ADSL line with a Cisco 887VA router attached. This has been working fine for the last couple of months. However, recently, the site have started to complain of performance issues (network slow, applications disconnecting, etc)Looking on the router, we can see evidence of packet loss/timeouts from a simple ping to the internet e.g. [code]
However, we have logged the fault with our service provider and they return all line tests as clear but what is particularly strange is that they also report “and the SNR Margins are well within threshold levels (Upstream 11.5 and Downstream 15.0)” which, unless I’m misunderstanding something, seems to be completely different from what the router itself is reporting.Is there a reason why the service provider’s stats for Noise Margin would appear to be so different from what the router is reporting?

We have several of the SG300 Serices switches. We use them to route VLAN traffic to Remote Offices, Internet Connections, and WiFi Access Points.In one remote office we have a SG300-10 setup to route the HQ Network and the remote Office Subnet. The SG300 is Connected to HQ via Fiber and has multiple Tagged VLANs on it. If I do speed tests over the Fiber Link on the Incoming Tagged Netwotk I get Decent performance, 80Mbs. If I switch to a networtk that is not priginating from HQ, and have the SG300-10 route packet, I get dismal performance. 15-20Mbs.
I Fireded up a New SG300-28P FW v1.2.7.76. Added a the HQ VLAN 101 and new VLAN 1025 . Mapped some Tagged and untagged ports for each. Switch was connected to HQ Network as untagged VLAN 101. I put a laptop on an Untagged VLAN 101 port. Ran some tests, cam back with 750-850Mbs. Great. Put the same laptop on a Tagged 101 Port, Configured the NIC for Tagged VLAN 101, Same test, same Speeds, 750-850Mbs.I then Configured laptop for Tagged VLAN 1025. Connected to tagged VLAN 1025 port. Ran speed tests, resuts were 15-20Mbs!
I then Configured laptop for Untagged VLAN 1025. Connected to unagged VLAN 1025 port. Ran speed tests, resuts were 15-20Mbs!It was only the Laptop and the Connection to the HQ net on the SG300-28P. Why is the performance of this unit soooooo poor when it needs to route?Other Switches have FW v1.0.0.27 or FW v1.1.2.0. They have Similar speed issues. All Configured for Layer 3.

I am having poor performance through an IPSec VPN between two Cisco ASA 5505s. In researching, I found some discussion about setting the MTU for the VPN. So from one side of the VPN tunnel, I tried pinging a host on the other side specifying the Don't Fragment flag and testing different packet sizes. I found that a size of 1398 is the largest packet size that results in a successful ping.So, I also understand that I should be able to set the MTU to 1426 (1398 + 28 bytes for the IP and ICMP headers). What I'm not 100% clear on is where all I need to set this. Do I set the MTU for the outside interface of the ASA that the VPN tunnel is going through, or do I also need to set the MTU for the inside interface, or on the outside interface and the switch port that the interface is connected to (switch port is set to an MTU of 1500 as well)?My thoughts are that only the outside interface of each ASA needs the lower MTU (currently set at the default of 1500).

We have two offices separated by a WAN.Office A is our main office that has all of our servers, including domain controllers and active directory, on our own network.Office B is a temp. office that is piggybacking off of our sister company's network, but the computers there still connect back to Office A servers to login/access services. However, Office B connects to the sister company's local domain controllers for DNS/WINS.We're having an issue where NetBIOS names of the other office are not always showing up when browsing for computers within the WinXP Windows Explorer (My Network Places --> Entire Network --> MS Windows Network --> domain A). It seems entirely random whether or not we can see the other office's computers. We can still ping/remote to them, but cannot browse to them.
It would normally be a non-issue, but some of our software apps require us to "Browse" to the network server location, rather than being able to type in the address, during installation. Can't install if we can't browse the Office A servers. Obviously has something to do with WINS not always populating/updating, but I'm not sure what or how to fix this.

I have 2 Windows 7 desktops that are both connected to seperate vonage boxes and those vonage boxes are connected to my D-Link DIR-655 router. That D-Link router is getting its connection from a Comcast router. I am looking to get one of the desktops to share a printer from the other one which has it hard wired via USB cable. When I first set this up I did not have the vonage boxes and the desktops were connected right into the router and everything worked fine. Now that the vonage boxes are in place it is a mess. I can get internet fine on both machines, but no file/printer sharing. I have followed all the steps to setup the correct workgroup and file and printer sharing options on both windows 7 machines but they cannot see each other at all. My feeling is that now that the vonage boxes are there that instead of the desktops looking at the D-Link router for its sharing option they are looking at the vonage boxes and that is why they cant be seen. Does this make sense? Is there a firewall on the vonage boxes stopping these two desktops from seeing each other? Do I have to change something on the D-Link router options for it to give access to the vonage boxes for these 2 machines to see each other for printer/file sharing?

I run a DIR-825 as an access point on my home network and I upgraded the firmware from 2.03Na to 2.05NA and it looks like it was a poor flash. Orange Amber power light, no wireless radios, unable to access it via its configured ip or default (192.168.0.1). It will not respond to pings, give arps, or obviously the web browser session.Is there any way to reflash these things manually or do I have to send it in?

I recently bought a dlink 825 and it seems right out of the box the wired internet connection seems very poor. Wireless works fine but it on wired the router refuses to download any files larger than 300kb. Images won't load, files won't downloads, etc. I've swapped cables, tried two different computers, hard reset, loaded the 3.01 firmware and nothing seems to work. I went back to my old router and it works fine. I am able to transfer from computer to computer okay with the 825,The cable modem is a SA dpc2100.

I have a D-Link DWA 510 and it's been perfectly fine, no hassles. Until about a week ago. Since then, not a lot has changed in my computer except for a new PSU/CPU and Keyboard and Mouse. Nothing has changed about the router, it's just the card that's messing up.
What I've tried:
Reinstalling the drivers
Updating
Rolling Back
Changing PCI card position
I'm up for trying many things. I just want some reliability until Saturday/Sunday when I buy my new card.

I have a DSL connection with AT&T. It is rated at 6Mbps / 768Kbps, but it closer to 4Mbps / 600Kbps. I have a speed stream 5360 connected to the DIR655. Devices on my network are primarily wireless and include; several laptops, a desktop (which is wireless n), a couple phones / Ipods and a Wii that I watch Netflix on.
I do a lot of Photography and a handful of video work, and backup / share everything online. When I am uploading photos, even with "conserve bandwidth" turned on in the uploading application, browsing sites is very slow, but reasonably functional. If I try to upload a video to YouTube, I can barely manage to do anything else the entire time it is uploading. I've tried to plan and run all my uploads overnight, but then Netflix is unusable when I want to watch it at night.
I've tried several different things, first off, with getting the Wii to function for Netflix, I turned on the QOS engine, for the IP that is assigned to it, and set it to priority 1 for all ports. I also have a entry in the QOS engine for SSH on port 23 with a priority of 10 because of how laggy my SSH sessions are. I do not have any other entries in the QOS engine, is that a problem? Should there be entries that cover other services and assign them a lower priority?
I have enable traffic shaping and Automatic uplink speed turned on. It measured the uplink speed at 695kbps, which is pretty accurate. I have Automatic Classification off, and Dynamic Fragmentation on. WISH is enabled also. I'm set to mixed n, g, and b, I'm not positive, but I do think my older laptops only use wireless b.
Even more importantly than the Netflix would be to allow me to use the Internet in a functional manner while I am uploading, that would solve a lot of problems. It seems that the uploads just hog every last bit of upload bandwidth and don't want to make room for even the small requests that one needs to send to view a web page.

I have tried 2 DIR-655 routers now, revision B1, firmware versions 2.04, 2.07, 2.08beta and a number of laptops and wireless mini pci-e nics and I simply CAN'T get faster than about 10 megabytes/sec transfer speed from a wireless laptop to a wired gigabit desktop.
Is this just simply a limitation of these routers? Can they simply not transfer data at decent speeds? I've seen real world transfer speeds near 12 megabytes/sec on a DIR-615 and I assumed the limiting factor there was the 100megabit wired connection.
I've spoken to a dozen different D-Link phone support workers

I continue to have significant performance and random reboots with DIR-825 router (hardware: Rev A1; Firmware: 1.13NA). My ISP has checked the lines to my cable modem. If I connect any of my laptops or PCs directly to the cable modem and work off the direct connect, all works fine with no problems for many days and even mutliple weeks. So, the router seems to be the bottleneck/issue.
I've tried multiple settings changes as listed in the forum here. My setup is fairly simple and detailed below.
Setup -> Internet:
-- Dynamic IP (DHCP)
-- I have disabled "Enable Advanced DNS Service"
-- "Use Unicasting" is enabled
-- I have primary and secondary DNS servers set
[Code]....
