I have a dir-655 xtreme N gigabit router with 2.03NA version firmware. The wireless signal will suddenly and randomly disappear from my laptop. I checked the ‘’properties’’ of the network connected … it remains on the same channel when it reconnects so I figure it’s not a channel issue.
 I have reviewed this forum for hours and have made many changes to my settings, but nothing seems to keep the wireless signal from stopping.

Computer: dell inspiron 6400
OS: windows XP pro (sp3)
ISP service: DSL
Modem: stand alone (Sagemcom 4300)
Router: dlink / xtremeN gigabit router / dir655
Set for mixed g, n and b  wireless mode
Security: wpa-personnal / TKIP
Firmware: version 2.03NA

Router settings:

I'm using the DHCP settings.
Turned off:  QoS, Advanced DNS services, Short GI

Firewall settings to Endpoint Independent for TCP and UDP.
DHCP reserved IP addresses for all devices on the router.
DNS IP addresses are being filled in under Setup/Internet/Manual.
DNS Relay under Setup/Networking is enabled.(tried it turned off and didn’t fix the problem)
My phones operate on 5Ghz.

I’ve been working on this for two days. What other tests can be done to fix the problem?
HELP!!!! My frustration level is peaking…..

Thank you for your concern!!!

Try single mode G or mixed G and N?
Any other WiFi routers in the area? Use InSSIDer to find out.
Turn off Extra Wireless Protection if you have it. Under Advanced/Advanced Wireless.

What ISP Service do you have? Cable or DSL?
What ISP Modem do you have? Stand Alone or built in router?
What ISP Modem make and model do you have?
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.

Still disconnect after trying proposed config.

Do you get any disconnect when directly wired to the router? Wondering if the router fully disconnects or if there is a problem with WiFi.

Let us know if you have any other WiFi routers near by...

Also on your ISP Modem:
SpeedStream 5100

disconnects when hardwired to the router but not if connected to the modem

[FurryNutz]

I see so it disconnects both wired and wireless.

Check the logs on the router, any specific entries when it disconnects?

I would swap out cables between the ISP modem and router and test.

Turn off the WiFi radio and test once more wired and see if it disconnects?

Maybe someone can review your router settings with you using teamviewer.

changed the cable by didn't solve the problem.

Whats the WAN port speed set for on the 655? I presume Auto, try manual 10 and 100?

Seems like the 655 is loosing connection with the ISP modem.
Any available log entries on the ISP Modem by chance?
Is this modem in standard mode or bridged mode?

Any chance you have a neighbor or friend you can take the router too and put it on there system?
One test you can try, disconnect the 655 and see if you can maintain a connection with the routers web page. I presume you should.

[GR]

If i'm disconnect from the router, I don't have any access to the router's web page...

Also, I tried to connect to  192.168.254.254.  to config my modem and the browser tells me this page can't be reached...

[FurryNutz]

Even when wired your not getting the routers web page? What browser are you using?
Same thing happen with Opera or FF?

Open a DOS command box and PING the ip address of the router and IP address of your network card. Any response back?

How about if you disconnect the router from the ISP Modem and just connect to the router and review the routers web page on a wired connection? If after this your keep loosing connection, I suppose the router is bad, after swaping cables, connections. When did you get this router?

You could try a FW update and reload the code and see if it will clear this up.
Any 3rd party security applications running?

[GR]

wan port speed is set at auto (10-100)

[FurryNutz]

Try manual 10 then 100 to test?

[GR]

Even when wired your not getting the routers web page? What browser are you using? Explorer 8
Same thing happen with Opera or FF? What’s this???

Open a DOS command box and PING the ip address of the router and IP address of your network card. Any response back? Don’t know how to do that….

How about if you disconnect the router from the ISP Modem and just connect to the router and review the routers web page on a wired connection? If after this your keep loosing connection, I suppose the router is bad, after swaping cables, connections. When did you get this router? Got the router last year but never been working good so I’m taking time to fix it now…. since I’m retired..

You could try a FW update and reload the code and see if it will clear this up. Already updated yesterday…
Any 3rd party security applications running? Only security is the one provided with windows and Microsoft…

[GR]

I'll try manual 10 and 100

[GR]

wan 10 or 100 manually set didn't solve the problem
