LG E450 wifi not working

[akashbothra]

There is a problem with my lg e450 wifi. Its wifi specification shows 802.11 a/b/g/n. My router is Dlink-dir-605l, supported protocols are IEEE 802.11n, IEEE 802.11g, IEEE 802.11b, IEEE 802.3, IEEE 802.3u. missing one is 802.11a. now whenever I am trying to connect to internet through mobile wifi, connection always comes and go. other devices are working fine with the router. Mobile reset didn't work, service center guys couldn't help. What shall I do???

>remove stupid battery savers from phone
>Check wifi sleep policy.
>Check if you;ve enabled something called "optimize wifi usage for battery"

if problem persist then probably its harware issue.
