Hi @BasilDV ,   It happened again in past 3 weeks, and i did factory reset the modem and re-configure it again for 2 times. First i tought because of 1 device sucking up all of the bandwith and i did set the download limit to 47800Kbps and upload by default (19800Kbps), but still it does not help. Since it just happened randomly.   I'm not really sure what caused this problem and i'm clueless and thinking this might be hardware issue. When i was still subscribed to TPG ADSL 2+ with my own modem, this problem never happen to me.   Thanks   Adut ... View more

Hi @BasilDV ,   Thanks for replying my post. My wifi channels and signals are good and the channels are far apart. The problem that i have when it happen is suddenly i have no internet connection (not only wifi connection but also with LAN connection). When tried to disconnect and re-connect wifi devices it won't connect and error mesage (on android device) is unable to obtain IP.    The current solution/workaround is to restart the router manually by pressing the on/off switch.  When i tried to restart it via the router web portal (via LAN connection) sometimes it give me an error pop out and then i'm no longer able to connect to router web portal. Another common issue is evey time i try to connect to router web portal it is slow to open the login page, clicking any of the options on the portal  also slow but couple of times chrome pops out error do you want to wait or kill the page because of the page is too long to open.   This issue is random but occurs quite frequently. It can be few days after restart or a week or 2 weeks. Before moving to TPG HFC NBN i'm using my own ADSL modem and this issue never occurs to me. Opening and logging in to modem's web portal is quick and i have no "unable to obtain IP" issue.   I hope you can shed some light with what caused my problem.   Thanks ... View more
