I am using a Broadcom 4313 802.11 wireless chip attached with my HP Dm4-060us wide screen laptop, this is running with windows 7 OS. This worked fine till the last few days, but suddenly form last two days either the wireless router or the chip is not working fine, whenever I tried to connect the router into my machine it responds that the router is not up to date and need to update the firmware version. I tried with all wireless mode, but nothing is responding, I am not having such information for the wireless connectivity. Is there anyone having any solution for this problem? Suggest me some tricks to resolve this one.
