I've tried everything you normally post in every other forums so here are the answers to those questions right off the bat. I switched to this router to see if the signal can go through our brick wall to inside the house better than the Linksys M10 that we got on black friday. I would like to keep using the Dlink since I paid for it already but it keeps dropping the Internet. Can you help me out with this one? I manage a computer repair shop and work with routers on a weekly basis. If there is anything you would like me to try just ask. I also have 2 more of these in the shop I could bring home to see if that helps.

Link>Welcome!
What Hardware version is your router? A1
Link>What Firmware version is currently loaded? 1.02
What region are you located? Tennessee United States

What kind of downloads are you doing? I can be doing nothing and it stops giving me Internet access.
Has a Factory Reset been performed? Yes every firmware update I’ve done I have done a factory reset.

What ISP Service do you have? Cable
What ISP Modem make and model do you have? I am using my own which is a Dlink DCM-202.

Some things to try: - Log into the routers web page at 192.168.0.1. Use IE, Opera or FF to manage the router. Always do since I’ve seen this post.
Turn off ALL QoS or Disable Traffic Shaping (DIR only) GameFuel (DGL only and if ON.) options. Advanced/QoS or Gamefuel. This is Off.

Turn off Advanced DNS Services if you have this option under Setup/Internet/Manual. Don’t have this option.

Turn on DNS Relay under Setup/Networking. Has a check which can’t be taken out.
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. I am trying this out now.
 
Ensure devices are set to auto obtain an IP address. Have always been set like this.
Set Firewall settings to Endpoint Independent for TCP and UDP under Advanced/Firewall. Don’t have this option.

Enable uPnP and Multi-cast Streaming under Advanced/Networking. Disable uPnP for testing Port Forwarding rules. Multi-cast steaming was turned off so I turned it on.

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 to Auto.

Set Time and Time Zone under Tools/Time. Why does mostly every setting change require a reboot? haha

Link>Wireless Installation Considerations

What wireless modes are you using? Under Setup/Wireless/Manual.
Try single mode G or N or mixed G and N? Trying G and N Mixed.

Channel Width set for Auto 20/40Mhz or try 20Mhz only. Set to 20 MHz.

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. Set to 6. All wireless connections around were 1 and 11.

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. WPA2 Only and AES in cipher type.

What wireless devices do you have connected? Cell phone is usually the only thing connected all the time. This could also happen with nothing on the wireless connected.
Any cordless house phones? Nope
Any other WiFi routers in the area? Link> Use InSSIDer to find out. How many? There are 4-5 but 3 of them usually display 0% signal.

Turn off WISH, and WPS under Advanced. Wish is off and so is WPS.

Try turning off Short GI, WLAN Partition,and Extra Wireless Protection if you have it. Under Advanced/Advanced Wireless. Just turned off Short GI.

Enable WMM Enable Under Advanced/Advanced Wireless. I can’t change this option but it is enabled.

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. I use Windows Firewall and MSE for this. I’ve never needed anything more. Internet works fine with my cheap black Friday M10 Linksys.

Turn off all devices accept for one wired PC while testing. I usually only have 1 PC connected when it disconnects. My laptops are usually off all the time.

Check cable between Modem and Router, swap out to be sure. Link> Cat6 is recommended. Checked. Cable works.

Was a factory reset performed both before and after sending the FW update file then set up from scratch?

Is both wired and wireless dropping Internet connections?

Advanced/Advanced Networking/WAN Port Speed to 100 and re-test.

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.

Test with a newer updated ISP modem? Motorola SB 6 series stand alone modems are recommended.
Ensure that your ISP cable line going to the modem is in good working condition and the signal levels are to spec. Have the ISP check this. The DCM cable modem is an older modem so it could be time to something new.

Yes I do the resets before and after.

Both devices are losing Internet but I'm thinking it happens when a wireless device connects to it initially is when it is dropping.

I will check the below setting when I get home and give it a shot and keep you posted. It happens about 3-4 times a day so you should hear from me tomorrow.

I have been using this modem for quite some time but like I said before the other router I used on it works just fine. I even switched back to that router for a week with no problems. I will look into getting a new modem. I have an older Motorola lying around for back up also.

Thanks for all the help.

One other test, you could take this router home and test it there to see if the problem follows.

Keep us posted.

Advanced/Advanced Networking/WAN Port Speed to 100 and re-test.

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.

Both of these settings have been changed to your specifications. This router is at my house. Unfortunately I can't take it to the shop and test it there so I'm stuck with just running tests here. Like I said though the other router does not have this issue.

Thanks for all the help. We'll see where this takes us.

[FurryNutz]

Keep us posted.

[Twotone]

Anything else to try. I've added a new modem and it is still disconnecting me. All the changes have helped because its not as often but it is still doing it.

[FurryNutz]

What Channel is currently being used? Is anyone else using it?

• If you have any of these options, Try turning OFF or ON Short GI, WLAN Partition, HT 20/40 Co-exhistance and Extra Wireless Protection if you have it. Recommended settings are default. Under Advanced/Advanced Wireless.

What wireless mode is currently being used?
What security mode is being used? Try WPA2 and TPIK only.
Set Channel Width to 20Mhz only and test.

[FurryNutz]

Maybe someone can review your router settings with you using Link> teamviewer if your interested. Its safe and secure.

[Twotone]

I sent you my login info. Just message me if you're going to log in.

[Twotone]

Thanks for the help this morning. I will let you know if anything happens.

[FurryNutz]

Sounds good. Hope it works well for you.
