where you live ? Over in MD their doing maintenance. I think it's something to do with upgrading for ipv6 

i'm guessing if your issue happen today, maybe it could be related to unifi maintenance. Try call their support to find out.

u need to inSSIDer to survey your wireless channel.maybe too many AP with CH 11

I applied online at TM website yesterday, today received a call asking me do i need the hypptv or just online only, so i say i just need to online, then she recommend me to take another package, 10mb for rm148 only, i was like 'huh', got such package? But before i can ask further, the line cuts off, and i cant call back as the number is shown 'private number'

So i think back, that 10mb rm148 should be maxis package without the hypptv, just after one day your personal info can leak out and another competitor call u to offer another package...memang TM boleh

TM DIR-615 is not stable. Sometimes connected but no internet access...need to use cable

What is the best alternative router? (and cheap too )

I always downloading..so need routuer can hold the huge traffic

Is that any problem if using stock firmware? Btw dont know how to flash custom firmware, will get this router soon.

For those who experience problem accessing internet after certain time using TM Unifi router.
Before you reboot the router to "fix" the problem, try spending a moment to troubleshoot by changing your device to manual DNS setting, e.g. to google public DNS 8.8.8.8

See if you are able to access internet after DNS setting change on your device. In my case, it works if I don't query the router for DNS request.

I noticed this problem with TM Unifi router if your device is configured to use the router as DNS server. e.g. 192.168.0.1 (which is the default DHCP setting). The router seems to have problem serving clients' DNS request after certain period of time.

Best is to disable DHCP on the router, and setup a different DHCP server on your network. I have a second Wifi router in my network (for WIFI roaming in my home) and that serves as the DHCP server to assign google public DNS server to the clients.

Without serving as DNS server, my internet uptime with the TM Unifi router is superb, without speed slowdown and etc even after a long period of time.

The asus RT-N12HP (2 antenna) vs TL-WR1043ND (3 antenna), asus still better? Have no idea how to check the performance.

I think is the unifi L7 router suck, cant get full signal within 10m, and the Asus router cost around rm209, is it worth to top up from TL-WR1043ND RM145?

No need usb lar, i just need the wifi only, LAN port also rarely use. Already order the asus router. Hope it solve my issue.

already tested 1 hour, so far so good, play game no more lag / dc, signal bar from 2-3 (unifi L7) to 3-4 (Asus) or maybe my wifi card lousy, still testing.

it also depends on your wifi receiver.

I also still using unifi free router i bought a high power wireless usb adapter straight full bar from previous 2 bars only

WN8200ND.

U change an expensive router but your receiver is crappy the conclusion will still be the same eventually.
