Kareem wroteCan you login to your router via telnet or SSH ? If so, try increasing the SNR marging from 10 to 13 and see if that helps.
I am always checking my line stats when the speed drops, it is always normal, SNR and line attenuation don't drop , I don't think it is noise related . But anyway i'll try to increase the SNR margin .
Is it possible the modem quality is bad ? Anyone tried this particular model : TP-Link TD-W8961N V3 ?
