Since a few days I get "ERR_CONNECTION_RESET" errors in Chrome and Firefox. Mainly with wikia.com and imgur.com
After trying a lot of different approaches DNS flush, switching to openDNS, Router / Modem reset, registry cleaning, disable anti virus / firewall and whatnot I came up with no solution as of yet. I'm pretty sure it's not my PC though, since I have similar problems from my mobile phone. PC is connected via LAN, phone via WLAN. I did a capture and noticed a couple of errors:
And a lot of red and black bars in general. (I'm a total WS beginner) I uploaded the capture to my Dropbox ( Link to capture file ) and hopefully someone can finally tell me what the hell is wrong with my network.

Looks to me like someone is preventing you from accessing certain web pages. E.g. if you filter on "tcp.stream==4" for the fourth TCP session you'll see that your GET request for "http://diealdor.wikia.com/wiki/Piixy" leads to a connection abort by a RESET packet from 22.214.171.124 (well, two actually), but right after that you get retransmissions for the SYN/ACK from that same IP. This makes no sense - if the server aborts the connection it won't try to resend "normal" packets afterwards.
What seems to happen is that someone is monitoring/intercepting your network traffic and injecting reset packets to force connections to fail. The server doesn't know about that, of course, and tries getting the real packets through to you, which is why you see them coming in after the resets. It's interesting that other web page calls (e.g. to imgur.com) work, so it looks like only specific URLs are messed with. I don't know what network you're on, but if this at work, it may be a "prevent employees from accessing non-business websites" mechanism, but that's usually done via filtering proxy, not forged resets.
So my guess is someone is messing with you, or just doesn't want you to visit certain resources. It must be someone with access to your communication, so check if there's something/someone in your own network who may be reponsible. Otherwise it would have to be someone outside your network who can monitor what you're doing. Maybe try to switch to HTTPS connections if you can, which makes it much harder to do something like this.
Of course this can also be some sort of misconfiguration, but the incoming packets after the resets are very uncommon.
