The Graveyard - Products No Longer Supported => Routers / COVR => DIR-628 => Topic started by: jrodgers1963 on January 06, 2012, 09:42:01 AM

I have had a DIR-628 for a couple of years now, and for the most part it hasn't given me any problems. Lately though I am experiencing regular Wireless signal dropout. IT is occurring on multiple wireless devices in our home. At any given time there is a Macbook, A PC laptop, 2 ipod touch, and an iphone sharing the wireless signal. When it drops, they all lose connection.
I have contacted our internet provider because I initially thought the problem was with the internet signal, but the Tech I spoke to was able to monitor my incoming signal and check on activity over the past week or so, and he said the signal was strong and showed no sign of a problem. We are using a Motorola Surfboard SBG6580 cable modem, provided by the supplier. Out if curiosity, I connected my Macbook directly to a port on the modem via ethernet, and I haven't experienced any dropouts since.
My Router is running as follows:
Firmware 1.24NA
2,4ghz
Mixed n and g
Auto channel scan
WPA Personal security
Auto WPA mode
Hopefully someone has some suggestions as to what might be causing this. IF you need more information about the router settings please let me know.
Thanks

Some things to try:
Ensure DNS IP addresses are being filled in under Setup/Internet/Manual? You can find these under Status/Device Info/Wan section.
Turn off ALL QoS (DIR only) GameFuel (DGL only and if ON.) options. Advanced/QoS or Gamefuel.
Turn off Advanced DNS Services if you have this option under Setup/Internet/Manual.
Turn on DNS Relay under Setup/Networking.
Setup DHCP reserved IP addresses for all devices on the router. Setup/Networking
Ensure devices are set to auto obtain an IP address.
Set Firewall settings to Endpoint Independent for TCP and UDP.
Any cordless house phones?
Any other WiFi routers in the area? Use InSSIDer (http://www.metageek.net/) to find out. Having other WiFi routers near by can cause issues like this. Find an open channel if there is one available and manually set it.
Turn off Short GI and Extra Wireless Protection if you have it. Under Advanced/Advanced Wireless.
-
Wow...lots of info! Thanks.
I've made all the changes you've suggested. Many of the things were enabled/opposite to what you mentioned, and the DNS addresses weren't where they should have been.
Regarding things like ipods, ipads etc. How do they fit with all of this?
I'll reboot the router now, and monitor things for a while to see if its improved.
-
Keep us posted.

Just wanted to update you...
Since you provided the suggestions for the router, I haven't been experiencing the drop outs I was before, and it seems that the signal strength and stability are much better also. I downloaded the app you suggested to monitor the signal strength, and its basically a steady flat line.
So far so good! Thanks again

Good to hear and glad it's working. Enjoy.

Hello again,
Just wanted to update the situation I was experiencing with my signal dropping. Things have been much improved since I followed your suggestions, aside from one PC laptop running Windows 7. It seems to still drop the connection a couple of times a day. Usually I"m able to just open the connections status tab and click Connect again, but it's a bit of an annoyance. I'm wondering if you have any suggestions? I have set it up as a reserved device, but it is using DHCP. Should I give it a static IP?
THanks

Need to set up reserved IP address for your PC ON the router and the PC should be setup for Automatic.
Also does the wireless adapter on your PC have any additional properties and options with in it's settings?
What wireless modes are you using now on the router?
-
Hi
The IP address is reserved on the Router for the PC, and set to Automatic on the laptop itself.
The Wireless adapter is an Atheros AR5893. There are advanced options as follows, but they are all set to default:
-802.11b Preamble
-AdHoc 11n
-Dynamic MIMO Power Save
-Network Address
-Recieve buffers
-Scan Valid Intervals
-Transmit buffers
If you have any suggestions for these....
-
Any sub options for these main ones your seeing?
There has been some issues with Atheros WiFi and some routers.
Is this an adapter that can be changed out or can you test with a different adapter to see? Something like a DWA model from DLink?
-
When I select the option there is a drop down to the right of it with some sub items...if you can give me a better idea of what to look for I can let you know.
Unfortunately, this is a built in adapter on a Gateway laptop, and I don't have anything else to test. All the other computers in the house are Macs.
-
Maybe someone can review those wireless settings with you using teamviewer. (http://www.teamviewer.com)
-
Sure...I have Teamviewer on there already.
That would be a big help.
-
Send me a PM with ID and password.
-
Router was set for mixed all wireless modes. Set for Mixed G and N and turned off Short GI.
Mentioned to turn off 3rd party firewall programs and let the router handle that.
Please report results after a few days.

I read with interest this post as I am having the exact same problems. My Dlink router has worked great for two years and then suddenly its been freezing up. I checked with my ISP and the problem is not on their end. Something is happening to freeze our router. I tried all the steps listed in this discussion and I am waiting to see if they work. While I wait for results, I have one question - is their a limit on the number of devices that can connect to the router at one time? I ask this because up until Christmas we never had problems with the router. At Christmas, we added two new laptops, an I-Phone and an I-Touch, all of which connect to the router. Today we had 10 items connected to the router - 2 desktop computers, 2 laptops, 1 Wii, 3 I-Touchs, 1 I-Phone, 1 Blackberry. I made sure to reserve an IP address for each, as instructed in this discussion. But is there a limit? Thank you,
Shaun

No doesn't matter how many.

It went about 3 days before freezing again. I made all the changes you suggested in this message chain. We dont have any other routers in our area (we live in a rural location) but we have 2.4 phones - two of them. I tried changing the frequencies that they operate on. Anything else I can do? I notice that this particular router can operate on 2.4 GHz or 5 GHz. How hard would it be to change to 5 GHz operation? Will all my devices still connect? Thank you.
-
Test with out the 2.4Ghz phones. They can interfere and cause dis-connections.
One thing to try is to set a manual wireless channel and see if this might help. Try 1 6 or 11.
-
Disconnected all 2.4 phones today and router stayed connected until this evening when it froze again.

What Hardware version is your router? Look at sticker under router.
What Firmware version is currently loaded? Found on routers web page under status.
What region are you located?
