Hi guys in a moment of desperation(out of my control) i had to buy a wifi ADSL router at Incredible Corruption(Was the closest shop and i'm lazy)
The Router works fine its a Tenda(eish i've never heard of it either)
But it works fine just one small problem, All pc's on wired Lan can ping each other but they cannot ping pc's on Wifi
So wifi pc's cant ping lan pc's and visa versa.

Again:
lan can ping lan just fine
wifi can ping wifi just fine

but:
lan to wifi no
wifi to lan nope
NO mixing!

Its like the old apartheid years and it's so irritating... the wifi laptops wanna go on strike now cause they cant stream lekka videos from the wired pc's... they're so sad and want to bomb the government, err i'm mean the router.
I'm sure its just a setting on the router but i've tried everything and i've upgraded to the new firmware as well. Nothing works, i cant understand why this would be the default setting! :mad:

Help US!
 
On some routers it's called "Wireless Isolation"
 
Does your Internet work on the WiFi devices?

If so, then you can try the following, which is a complete hack, which me and my friends have done on a wireless network to get P2P working :D :
If your router is on 192.168.1.1, and your LAN PC is on 192.168.1.100, and your WiFi PC on 192.168.1.101
Then run the following on the LAN PC: route add 192.168.1.101 mask 255.255.255.255 192.168.1.1
and on your WiFi PC: route add 192.168.1.100 mask 255.255.255.255 192.168.1.1
Now try to ping between those 2 PC's...

This problem that you're having seems to me like the router is placing the LAN & WiFi devices on 2 different VLAN's.
If you can post a link to the manual & technical docs of the router, then I can have a look at its settings for you.
 
Some routers also allow a 'guest' mode over wifi, which means they are isolated from the network and can only use the Internet

Their support forum is a no go too:

We're sorry, an internal error occurred that prevents the request to complete.
Our supporting staff has been notified with this error [I seriously doubt that] and will address this issue shortly. We profusely apologize for the inconvenience and for any damage [????] this may cause. You might want to try the same action at later time.
 
I've gone through the manual and I can't really find anything, except that the firewall might cause issues.

I would suggest that you try my hack that I've previously posted to see if that doesn't solve your problem.
 
Cant seem to write the command correctly... your example(add mask etc) just brings up the same help menu as typing "ROUTE ?" in the cmd

To answer some of the other questions: DHCP is enabled and all pc's are on the same subnet mask.
wrt the windows 7 homegroup, Yes all pc's run windows 7 but since they're unable to ping each other they cant join the same homegroup. The LAN pc's can have their own homegroup while the WIFI pc's can join their own homegroup. The two don't see each other's homegroups.
 
googled similar and some guys suggested turning off "homegroup" completely, rebooting and retrying. not sure of success rate though.
 
Could you perhaps copy & paste the 'route add' command that you're using, because I find it hard to believe that it's not working / giving the help menu.

Alternatively, you can try to manually set the IP address on the PC, by using the same values as given by the DHCP server, except that you change the subnet mask to 255.255.255.255 instead.
You'll need to do this both on the LAN & WiFi devices.
