Title: Help! Loal Network is not working on DIR 655
Post by: James on July 22, 2009, 02:13:06 PM

Hi,

I just got my DIR655 a week ago. I used it as router to connect my 3 computers at home and uplink is DSL Modem.

All my computers can connect to Internet without any problem, but they can't connect to each other:
- they can't ping each other's IP
- their name can't be resolved to IP address properly
- they do not show up on other computer's Network.

When I log on the DIR 655 management web site, I can see all 3 computers are connected and assigned Dynamics IP address.

All my computers are in 192.168.3.x IP range with subnet mask 255.255.255.0, and my router's IP address is 192.168.3.1, it shown as default gateway for all my 3 computers as well.

I have tried disable firewall, disable anti-virus software etc, none of those approaches helps.

any suggestions/clues?

1 computer wired and 2 wireless.
the wired cannot ping wireless, and wireless can't ping each other.

I even put one of my laptop on wire connection, still not working:
the two wire computer can't ping each other

please help

A few questions for you as not enough info for us to help.

Are you using MAC filtering? ( have you plugged in all the computers, wired and wireless MAC addresses)

Dose your Dsl modem have DHCP enabled? ( if so is the dir 655 DHCP server unchecked?)

Is NetBIOS Announcement checked? (setup-->network settings)

Is Dynamic Fragmentation unchecked? (Advanced-->Qos engine setup)

MAC filtering == No
DSL DHCP == Yes && DIR 655 DHCP ==  Yes
NetBIOS announcement == Yes
Dynamic Fragmentation == Yes

Which settings do I need to change?
Thanks!

Mac filtering-yes ( takes a few minutes to plug in the numbers but also helps with security)
Dynamic Fragmentation-no uncheck it
NetBIOS announcement == Yes leave it alone
DSL DHCP == Yes && DIR 655 DHCP ==  no (after you get MAC filtering done , uncheck it. causes double NAT.)
