Help analyzing packets


I need some help analyzing the capture. My system is having some major issues pages will load funny sometimes and other times it doesn’t get a DNS response before it poops out. I see TONS of Red on black packets in wireshark. This capture is just a small 7 second capture of me accessing my router’s configuration page.
Do these typically mean a bad cable? bad NIC? what’s going on here?

Thanks for any help given!!!

you can find my capture here. it is in standard pcap format

I’m not sure of any pcap exploits but if there are any and you’d prefer screen shots let me know.
