padmakunal, the 14.30 error code is known to occur when your ISP (Internet service provider) updates or changes settings in your router without your knowledge. You need to ensure the wireless mode is set to b/g/n and not g/n. You may be able to get them to do it or post your ISP and make and model number of your router and someone here may be able to help.
renojim Thank you for your reply. I called Xfinity who is the ISP and the support guy said my router is older version so they need to replace it with newer version. I will update this reply once I test with the new router and see if it fixes the problem. Appreciate your help.
