I have personally added conduit/flexible hoses to the fiber optic cable for extra protection.

I have added installed a stand fan blowing straight onto my routers and BTU for cooling. Worried they give way so the extra stand fan really helps cooling them down + my notebook.

I strongly believe an additional fan is necessary if you want to extend the BTU and wireless router life span. Once the warranty is over the BTU replacement is going to cost an arm and leg.

BTU got lifetime warranty.

Try changing the wireless channel by logging into the wireless router.

Can... i send and receive fax all the time...

after online 19days with new router (TP-LINK WR841N) without problem, got to turn off the router today coz of changing some electric system..
nice router with reasonable price.. eventho 19days online, no issue happened.. everything smooth.. just dreaming to buy Mikrotik router but ending fall in love with TP-LINK coz my previous streamyx modem+router also TP-LINK..
when i bought it, i didn't flash to klseet firmware coz already Unifi compatible and the firmware inside it newer than klseet firmware.. using it without problem.. IPtv at LAN port 1..

well if yr concern is fax, yes it works with unifi phone line. RJ11 cable comes with the DECT phone.

to unifi user,

wanna ask if blackout, u still can use the phone?

One word: "lazy"

Say "cannot be done", kautim.

Say "can but I'll need to call for help" = a lot more effort and time used for the same pay and possibly miss the next installation and associated commission.

See, even typing that takes more effort. LOL.
