DIR 655 Disconnects several times a day
« on: June 17, 2014, 11:50:09 AM »

Hi!

I made a new thread after I realised this is the European section of the DIR 655 support group. Sorry.
I would love some help here. I'm having troubles with my router. It's a DIR-655 A4. I feel ashamed but i never updated my firmware on my router till today. I had 1.20EU (2008 version) since i bought it. A few days ago my ping randomly went up to 8000 and i had to unplug the router each time and the problem went away for a bit. I looked up some things on this forum and performed a few tweaks. It seems more stable now but I still have the same problem with high ping. I changed the firmware to 1.37NA (the dlink support page led me to this update) but Im from Europe. Can it cause problems ? If yes can I change the firmware to EU? I didnt preform factory reset after updating the firmware either. Can someone please help me out here ? I'm so desperate. I called my ISP too and they will send some guys to check if there is a problem with splitters, or the modem itself. I would really appreciate some support here. Thanks in advance and sorry for my bad english.

edit: I also have these weird numbers on the wireless statistics page:

Link>Welcome!

  • Are you wired or wireless connected to the router?
  • Was a Factory Reset performed before and after any firmware updates then set up from scratch?
FW Update Process
  • Was the router working before any firmware updates?

Internet Service Provider and Modem Configurations
  • What ISP Service do you have? Cable or DSL?
  • What ISP Modem Mfr. and model # do you have?
  • Is ISP Modem/Service using Dynamic or Static WAN IP addressing?
  • What ISP Modem service link speeds UP and Down do you have?
  • Check cable between Modem and Router, swap out to be sure. Link> Cat6 is recommended.
  • Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask. Link>Checking MTU Values


Router and Wired Configurations
Some things to try: - Log into the routers web page at 192.168.0.1. Use IE, Opera or FF to manage the router. Besure to log into the Admin account on the router.
  • Turn off ALL QoS or Disable Traffic Shaping (DIR only) GameFuel (DGL only and if ON.) options, Advanced/QoS
  • Turn off Advanced DNS Services if you have this option under Setup/Internet/Manual or under Setup/PARENTAL CONTROL/Set to>None: Static IP or Obtain Automatically From ISP.
  • Enable or Disable Use Unicasting (compatibility for some ISP DHCP Servers) and test under Setup/Internet/Manual. Disable may help with speed performance on higher speed ISP services.
  • Turn on DNS Relay  under Setup/Networking. Link>Finding Faster DNS Addresses using Name Bench and input new DNS addresses under Setup/Internet/Manual.
  • Setup DHCP reserved IP addresses for all devices ON the router. Setup/Networking. This ensures each devices gets its own IP address when turned on and connected, eliminates IP address conflicts and helps in troubleshooting and maintain consistency for applications that need to connect as well as mapped drives.
  • Ensure devices are set to auto obtain an IP address.
  • Set Firewall settings to Endpoint Independent for TCP and UDP under Advanced/Firewall. Enable or Disable SPI to test.
  • Enable uPnP and Multi-cast Streaming under Advanced/Networking. Disable uPnP for testing Port Forwarding rules.
  • Turn off WISH, and WPS under Advanced.
  • WAN Port Speed set to Auto or specific speed? Some newer ISP modems support 1000Mb so manually setting to Gb speeds can be supported by the router. Advanced/Advanced Networking/WAN Port Speed
  • Set current Time Zone, Date and Time. Use an NTP Server feature. The DST setting is only needed in the NA region. Tools/Time.


Wireless Configurations
Links>Wireless Installation Considerations and Managing Signal Congestion and Good Neighbour Policy
  • Ensure the default (dlink) SSID name is changed. Can be anything and not something that's already in use by any neighboring WiFi routers. Under Setup/Wireless/Manual.
  • What wireless modes are you using?
  • 2.4Ghz Routers only: Try single mode G or N or mixed G and N?
  • Channel Width set for Auto 20/40Mhz or try 20Mhz only.
  • Try setting a manual Channel to a open or unused channel. 1, 6 or 11. 11 for single mode N if the channel is clear. 13 for EU regions.
  • What security mode are you using? Preferred security is WPA-Personal. WPA2/AES Only. Some WiFi adapters don't support AES, so you might want to try TPIK only or Auto TPIK and AES.
  • What wireless devices do you have connected?
  • Any 2.4Ghz or 5Ghz cordless house phones or WiFi APs near by?
  • Any other WiFi routers in the area? Link> Use InSSIDer to find out. How many?
  • If you have any of these options, Try turning OFF or ON Short GI, WLAN Partition, Extra Wireless Protection and HT 20/40 Co-existence if you have it. Also testing with HT20/40Mhz Co-existence enabled will impact results as well. I prefer to use this option OFF. Recommended settings are default. Under Advanced/Advanced Wireless.


Router Placement
Forum User - "Well I feel really dumb. After moving the router away from other electronic devices my speeds are back to normal. Just a heads up for anyone experiencing slow speeds, you might want to move it away from other electronics and see if that helps."
3-6' feet minimum safe distance between devices.
Placement on main level floor and central in the building and WELL ventilated is preferred. Not in basements or closets as building materials, or near by electronics devices could interfere or hinder good signal propagation.

Hi ! Thank you for the fast reply !

Only wireless connection.
I didnt perform factory reset after the firmware update. Can this be a problem ? Can I preform it now/ It helps ?

The router was working fine. I experienced the first problem a week ago.

I have Cable ISP service.

I have a CBN CV6181E type modem.

Im using g and n wireless mode now, But it was b/g/n i changed it, but the problem still occurs.

I checked nearby routers with inSSIDer. Theres no router using the channel im using (channel 3). It was auto on my setting, now I changed it to channel 3 only. No cordless phons around

The modem is bridged to the router (on the WAN IP adress field there isnt 192.168.2.# number)

Is it a problem that I updated with the 1.37NA firmware instead of EU ?

I only play Dota 2 on my laptop with wireless connection. The ping randomly jumps to 6-7-8000 from 12. When it happens I cant acces to my router through 192.168.1.0

I recommend always doing a factory reset, upload FW, factory reset and set up from scratch. This ensures a good FW update is applied.

I don't recommend using chl 3 as this is a over lapping channel that maybe still used by other neighbors.

How many other neighbors do you have total near you?

Recommended channels are 1, 6, 11 and 13.

Is TS and QoS enabled?

What can I do in this case I forgot to do a factory reset ? I used the 1.37NA firmware even though Im in Europe, is this a problem ? Should I update the firmware to the 1.37EU version ?

I have 5 neighbours. The inSSIDer shows 5 routers in the area. 2 of them using the channel #6, one using channel #11, another one channel #1 and the last one using channel #8.

QoS and TS both enabled.

I have these numbers on wireless statistics page:
 Sent :3017156
TX Packets Dropped :8636
Received :1170767
RX Packets Dropped :7359
Errors :1345

Do they mean anything bad ?

edit: I changed channel to #13

Ah, that could be the problem, You need to use the EU version if your in the EU region...
Download the EU version. I would factory reset the router, attempt to manually load the file using the routers web page. I hope it will take. If it does, factory reset again then setup from scratch.

Use and follow this please:
FW Update Process

Let us know how it goes.

I downloaded the EU version. I made a factory reset. When i want to upload the new firmware file i get this message:

The uploaded firmware file may not be correct. You may have uploaded a file that is not intended for this device, or the uploaded file may be corrupted.

If the uploaded file is correct, it is possible that the device may be too busy to properly receive it right now. In this case, please try the upload again. It is also possible that you are logged in as a 'user' instead of an 'admin' - only administrators can upload new firmware.

The Gateway will not be reprogrammed.


I downloaded this file from this link: http://www.dlink.com/uk/en/support/product/dir-655-wireless-n-gigabit-router?revision=deu_reva

I cant upgrade it to EU

Thanks!

Im sorry but I dont really understand these steps and I dont wanna **** it up so i ask:

Can you explain like I'm 5 these steps:

1.  Plug the Ethernet cable that connects your computer, that was plugged into one of the LAN ports,
2. Setup your PC with static IP - ex: 192.168.0.2 (different from 192.168.0.1)


I have plugged the UTP cable into the LAN 1 port and the other end to my LT.


edit: I scrolled down to the updated post of emrgency recovery. The only step I dont know is how to setup my PC with static ip.

Control Panel
Network and Sharing Center
On left sidebar, click manage adapter settings
Right click wired connection, then click properties.
Open the IPv4 connection.
The top section is the IP address and will be set to Auto Obatain, Select the Manual IP address.
Enter in 192.168.0.49 for the IP address and 255.255.255.0 for Subnet and 192.168.0.1 for Gateway. Save the setting and Ok all the way out from this window.

I did the exact same steps, but I couldnt get the Succes page. After I changed to static ip I opened a Fire Fox browser page, and typed 192.168.0.1 my after I got a message to wait and the router login page loaded.
What did I do wrong ?

When I unplug the router, then press the reset button, keep holding it and then plug it back again... So i hold it but no amber power button blinking. Just the blue power button, but it not blinks.

Keep the LAN cable connected between the router and PC.

I think the blinking needs to happen before you can get to the recovery mode...Doing this wont hurt the router. What your trying to do is get the recovery mode to engage on the router, when this happens, you open up the routers web page in the browser and you'll see the recovery mode on the screen as seen on the pic, or should be something similar.

I did the same steps but doesnt seem to working. No amber light blinking.

Do I have to unplug the Ethernet cable that connects to the routers "Internet" (next to the usb) port and the other side to the modem ?

Don't have to but you can try that...
If you can't get in, I'll check with my Rev A at home some and see if I can get in. I know Rev B and C routers do. Not sure about Rev As though.
