Hi guys,
Very new to the forums and excited to be a part of a networking minded community!
Anyway, to the point. Over the past 4-5 years I have seemed to have some serious bad luck with routers and modem-routers either dropping connections from the Ethernet ports or completely dying.
Some background info:
The first 2 modem-routers I had were Netgear Wireless-G DG834G both of which gave up working entirely a little over a year from setup. I sent them back under warranty.
Since the last Netgear I lost all faith in that brand so I bought a TP-Link N600, this worked great until it didn't. Unfortunately I lost the receipt so no warranty

Despite this I bought another TP-Link N600, thinking it may have just been a one-off hardware thing, based on all the great reviews it got. It's currently still going strong, although for some reason I couldn't connect to it via Ethernet for a couple days, that has since resolved itself...
For the router problem I bought a TP-Link Archer C9, this worked fine until all connections were dropped and upon inspection, noticed that all indicator lights were quite dim, so opening it up I found the voltage across the LED's to be around 2.5V which I assume is not its operating voltage and I suspect it may be a symptom of a fault somewhere else. I once again put my trust in TP-Link and bought the same router a year after the previous one and within 6 months all connections were lost again, although the LED's seem to be the same brightness as new.
All of the above routers and modem-routers are located in open environments with no heat traps surrounding them and there is at most 4-5 devices connected to any one of them.
I'm really starting to wonder if this is normal to keep going through routers so often or I'm just really good at picking lemons OR I'm the lemon when it comes to setting up a home network (highly probable).
