Buffalo Wi Fi router Problems

[suny]

Hi,

I am using Buffalo Wi Fi router (WHR-HP-G300N) connected to MTNL broadband connection.

I have connected following devices to the Wi Fi Router:

Laptop

Android Mobile Phone

Windows Mobile Phone

Android Tablet

Few weeks ago both the phones & the tablet were not able to access internet.

The notification on mobile/tab showed that it is connected to the wi fi router & the connection strength is excellent.

On the other hand the Laptop was working fine & accessing the internet as usual with good speed thru the router.

I did a factory setting on the router & all the devices started to access the internet once again.

Today the same problem cropped up again & now even factory setting the router is not helping. (None of the mobile/tab are able to access the internet. Laptop is accessing internet w/o any issues).

Also checked MTNL modem by connecting laptop to it directly thru LAN cable, it is working fine.

What could be the problem ?

Is the laptop wired to the router ?

what happens if you close and open wifi on the phones, does the connection come back.

often/usually the laptop is connected to mtnl modem thru lan cable where as the phones/tab is connected to wifi router.

but many a times laptop is also connected to the wifi router alongwith phones/tab.

PS: had powered off router & modem for half an hour & now after switching on, all is working fine.
