Just let TM do it. Never trust those outside installer. I used to let them do that and then until one day TM tells me that the port is unusable for internet. And I was like WTF, I already paid the installer money and I need to pay TM again because it is not usable?

TALK TO YOUR MANAGEMENT. u paying maintainance fees probably need to get entite building tenant voice out.

Cat 5 telephone line? Did you type it wrongly?

Cat 5 is LAN cable (RJ45), used for internet only.
Telephone Line is RJ11, used for internet and telephone.

Typically for highrise it would be RJ11, your normal POTS wire.  This normally adds about 20ms latency vs those that use fiber.

RJ11

Good to hear that. May I know who installed the cable for you?

If I remember correctly your issue is no copper wire installed for your unit right? So the contractor install new copper cable ?

TM quoted you RM230 but your contractor quoted you for RM180? Am I right? I forgot the price ady.

Oh. So your Management doesnt want to take any responsibility?

Request for one C5.

You can try call 100 to complaint about the wifi connection issue, 1st they will try to solve the problem through phone, if still cant be solve, they will send a technician to come over to solve the issue.

But it depend on the tech whether to change for you and whether they got the C5 on hand

For my case. when the tech come over to solve my phone line issue, i told the tech that the Dir-850L coverage not good, then he just give me the C5.

I don't have any problem with the DIR-850L.

bolehlaaa..that router almost RM400 if outside...
