Problem with wireless connection
« on: March 07, 2010, 04:06:32 PM »

what the fu*k means with this...
Wireless system with MAC address xxxxxxxxxxxx disconnected for reason: Received Deauthentication  ??
its crazy, i have to connect to the router over and over again, so annoying. whats the problem?
any settings i have missed?


example 2:
SIP ALG rejected packet from 192.168.x.xxx:5060 to 88.131.xxx.xxx:5060
but my IP-phone works great, but i want to know why my log is getting full very quickly.
I have already done a portforward on the phone, the phone uses UDP 5060 and 5004

??

What firmware version are you using?

Are you using the DHCP reservation feature in the router setup page?  If yes, the laptop still has to renew the address when it expires.  The router just gives it the same address every time.  If you manually entered that data into the Windows TCP/IP configuration settings and that IP is outside of the DHCP range on the router, then there is no need to ever renew it.

I think I said that right.  :)

Yes i am using the DHCP reservation in the router, for all of my computers. But i dindīt need to ype in the internal ip adress in windows. I am using firmware 1.30EUb08   and my desktop computer has no problem, it works fine, the internet connection has never failed. But i think it might be something with wireless settings, i am using (802.11n and 802.11g) and i turned back to (WPA or WPA2) and (TKIP and AES)
whatīs the difference between using WPA 2 onyl and WPA ?
I have a new laptop and it supports WPA2 i think, but what happens if my friend tries to connect to the network?
isnīt it better to have it on AUTO ?

Please beggin you, i have a serious problem. My laptop disconnects often. typical is when i turn the computer to "standby" "sleep mode" and when i turn it on again i must connect to a network, and it doesnīt find anything. I have another wireless network at home and that one works great.
I have now only one wireless network and the router is dir655 and i think itīs something in it that must be changed, but what? my other dektop computer works great. shall i do a DHCP reservation on the laptop? shall i disable UPnP ? whats wi-fi protection for? do i need it? i have now (802.11n and 802.11g) (WPA and WPA2) (TKIP and AES)
im using 1.30EUb08

You mentioned above "...my desktop computer has no problem, it works fine, the internet connection has never failed."

It sounds like your laptop has problems when coming out of standby and sleep; the WiFi card does not re-initialize properly.  Maybe a BIOS update would fix this?

You have several scenarios going on here at once.  The best/fastest/most secure configuration is WPA2 Only and AES encryption; this is what D-Link recommends.  If you have older devices that can't find your wireless network with this setting; then you might want to try WPA and TKIP.  My Aunt has some older WiFi devices that don't like "WPA2 Only", which does what it says.  Only WPA2 can get in; everything else is denied access.

I'm not 100% sure what Auto really does; someone else may know this feature better.  It either switches to WPA when it finds a device that doesn't like WPA2, or maybe it works with both at once.  Anything other than WPA2 and AES is going to be slightly slower, and less secure.  But if you can't use that; stick with WPA and TKIP and see how it works.

i have now changed to (802.11n and 802.11g) (WPA2 and AES).
is the statics in the webinterface telling the truth? i mean, it says rate 217mbps and signal between 54%-80%
someties it goes down to 108mbps and 54mbps but when i klick on a video in youtube it gets up to between 150-250 mbps. there are a big wall between my laptop and router.
