Hi all, thanks in advance for reading. Here is the situation. Two days ago the internet started getting really spotty. Just fine one minute (speed test showing ~20 Mbps), the next minute basically nothing (spotty graph maxing out at 1.2 Mbps). But this would only last ~15-20 minutes, and for school I use a lot of simple webpages that don't require much bandwidth. Well last night it lasted about 4 hours and literally couldn't even load a single page. So I reset the modem - still nothing. Called TWC they reset the modem from their end, said they were not getting any errors etc. etc. etc. Sent me up the ladder and had me connect directly into modem via ethernet - bam 20 Mbps again. Technician says, sorry it's the Airport. Before we got off the phone I reconnect the Airport and run another speed test: 20 Mbps over Wifi. Technician says, "Well it is probably just starting to go out - the modem is fine - bye." Now the Airport is probably at least 7 years old...I really don't know what the life expectancy is for one - but I've had modem after modem go out on me...and I suspect (and hope) it's the modem (it's a rental...don't hate me). How can I confirm either device is bad, and prove to TWC it's the modem if that is, in fact, what it is? Thanks!
