Hi,
if you look back the chat history early, you will notice that initially I also thought that to renew the TM contract to get a free router and use first.
Unfortunately, the TM gave me this Netis router instead of the Dlink 842 (this Dlink spoiled after 1 year plus).
I have used it around 1 week plus time without restart is working fine except the wifi signal is crapped, the range is too short and there is no free and custom DDNS services(I required it for my NAS connection). I connect it with another AP for better wifi connection (the Asus RT-N14UHP wifi is much better than Netis, except it has no 5Ghz connection).
its ARP table and the connected clients list is always unable to show all the connected client.
I am totally getting mad for the Netis actually. That is why I posted message to those seniors guys who advised me before, I should take their advices initially.
I am really regret. end up, I get the Asus AX3000 although I just renew my contract, problem solved (although its firmware still have slightly issue), now can relax.
Get back to your problem, personally I don't think you can stand with your current situation long.
The choice is still with you, just hope that you wont be like me. Maybe you want stand current situation longer to wait for the Wifi 6E coming also can.

Thank you to you and others advice , I have already renew and take their router so what I can do it just use it 1st before this I though of
buying a new one but I do not have the budget actually , currently I want I have wait and collect money to buy it . We are same boat 😅
