Yesterday when I turned on my PC the internet connection didn't work. It shows my connection as "Unidentified network" in the Network and Sharing Center and when I tried the Windows Network Diagnostics tool it said that "Local Area Connection" doesn't have a valid IP configuration. I googled around a bit (on my phone's 3G) and tried several fixes to no avail. Then I tried using the WiFi that's provided by the same router (Cisco EPC3825) which worked flawlessly. I tried my girlfriends PC which is connected via an ethernet cable as well and it had exactly the same problem as my PC. I checked the router's summary of connected devices on my laptop and it only showed WiFi devices (Chromecast, tablet, 3 phones and the laptop). My conclusion is there has to be something wrong with the router.
I haven't touched the router or it's settings between the connection working and not working, but there's always a possibility that our 8-week old kitten has been tampering with the router while I've been at work. I don't know.
I'll post here the (hopefully somewhat relevant) specs and the ipconfig.
My PC:
Gigabyte GA-990FX-UD3 rev 4.0 mobo
AMD FX-8320 CPU
Crucial Ballistix Sport DDR3 1600 2x4Gb RAM
PowerColor Radeon R9 270X PCS+ GPU
Samsung 840 EVO 240Gb SSD
Seagate Barracuda 2Tb HDD
Samsung Spinpoint F1 500Gb HDD
Corsair CX600M PSU
Windows 7 Ultimate 64-bit
GF's PC:
Asus M5A97 R2.0
AMD Phenom II x4 955 BE CPU
Kingston ValueRAM DDR3 1333 4x2Gb RAM
Samsung Spinpoint F1 1Tb HDD
Sapphire Radeon HD7850 GPU
Antec EarthWatts EA500 PSU
Windows 7 Ultimate 64-bit
Laptop ASUS X54C
Also connected to WiFi are a Nexus 7, a Nexus 5, a Galaxy Nexus, an iPhone and a Chromecast,
Router:
Cisco EPC3825
I don't know if this should be called a router, it's a cable modem with 4 ethernet ports and WiFi. I'm not familiar with networking technology (and even basic lingo) at all.
My internet connection is a 50 meg broadband connection provided by DNA Welho (a local ISP here in Finland) which has worked pretty much flawlessly since I moved into my current apartment a year ago.
ipconfig from my PC:
So my question is: Is there something I can do about the router or do I call my ISP for a replacement? Or is this even about the router?
Please ask me for any info I might have forgotten, I have been wrestling with this damn problem and 98 more since I got home from work 6 hours ago and I don't feel exactly right in the head. I need some coffee and nicotine.
