Arris G34 keeps dropping internet

Hi,

My Arris G34 started having internet connectivity issues since last 2,3 weeks. It was working fine for the past 3 months but recently it keeps dropping internet and the router restarts quite often (sometimes 2,3 times within an hour).

I tired another modem (hitron coda) with a separate TP Link router which does not have such issue. I have been using that for the past 3 days with no issue.

Hence, the culprit is definitely Arris G34. So my question is how can I fix my G34. I read in multiple threads that it can be a firmware issue. The g34 shows AR01.05.020.13_032624_735.NCS.20 as a firmware version. Is this the latest firmware? Can someone help on this matter?

Thanks
