how to change streamyx wifi modem name?? currently the name is "butter"

could not find unifi thread... i call TM cust service unifi 3 times today.. asking either there is any service interruption in my area... they said, not.. and i feel my line was spiky.. and i did tell them... they jz said... do normal troubleshooting dont know whats wrong. they even reset my port and my line, still the same

see this

even my speedometer shows my download speed is 4.34mbps and upload is 3.12mbps.. but see the ping... and while on youtube, loading so slow.. in game so lag..

could it be related with modem? i did tell them might be somethings wrong with the modem.. but they say, its not the modem.. calling them, waste my credit still the prob the same

i call them again and again. still not solve. they even argue with me related with the tel no not in unifi list. dafuq.. thn let me wait for 10 min.. thn they the one that wrong type the info i gv.. wasting my credit. eat more than half of my credit to call them. normal trouble shooting..i jz follow.. but still the same. i just complain to consumer rights
