Hi,

 

I have 90mbs speed plan fttb.

I have experiencing slow internet all both lan and wireless in these few days, the speedtest download is averaging 10 to 20 mbs. normally i have around 80mb average s. the upload speed seems to be ok though which is weird. I have power cycle the modem few times and check different cable but it did not fix the problem, please help I really need my downaload speed to be back where it used to, thank you for your help
