I just solved the strangest tech problem I've ever come across. My wifi kept dropping packets, confirmed by ping. It would look something like the first image (packets dropping, then it comes back to life). After a while the connection would just stop working completely and drop
Well this blew up! Might as well plug my business. Do you need social media management, content creation or video to help promote your cybersecurity-related business? We do socials, blogs, whitepapers, CTF challenges, webinars, influencer partnerships, SEO, you name it!
@hakluke I had a situation where wifi would keep closing up a channel, making my devices switch. Turns out, some of the ship's radars were causing interference, as I am living very much seaside. I only figured it out because when I would close my drapes, wifi would be working great
@florisandrei That's insane wow
@hakluke Just but properly shielded HDMI, otherwise you have the weirdest antenna connected.
@manchatz This cable was expensive but clearly for no reason! How do I find a good one?
@hakluke @SwiftOnSecurity Ok, this is interesting. I wonder if this is part of a problem I’ve had for a few years now. I have a Sony HT-Z9F soundbar with rear bluetooth speakers and subwoofer. The only things plugged into it are AppleTV via hdmi, and an ethernet cable for updates. The atv is also
@mcdev @SwiftOnSecurity sound bars are notorious for emitting ridiculous amounts of EMFs
@hakluke My monitor loses HDMI signal when I roll down window blinders, go figure
@DoctorLex I'll believe anything at this point
@hakluke I know of a printer that would start messing up every time the elevator would pass by its floor
@instantfinality no way that's crazy 😂
@hakluke God damn, man! This might be the solution to my problems! Thanks for posting.
@QAThomasNoUnity I hope it is!
@hakluke anything and everything can be an antenna bro
@aphelionpress1 good motto
@hakluke Yes it also happened in the early days of Raspberry Pi 4 where its 2.4GHz Wi-Fi will get jammed if HDMI is outputting 1440p60 https://hackaday.com/2019/11/2...
@FullyOrange someone else linked me a blog about this too!
@hakluke I had the same issue with a DP to DVI adapter. My router was literally in the same room. Monitor on programmatically - 5 GHz wifi is immediately lost. 2.4 is fine. Monitor off - wifi comes back. Pain in the ass to debug it. And a huge surprise when I figured out the root cause
@1ce_cream_p1e eyyyyy this is what i love about the internet I can actually meet someone with the same weird issue
@hakluke Yup. EMI (ElectroMagnetic Interference) is a real thing. You'd be shocked how many times I've fixed weird problems with a ferrite core. I discovered one day my window-mounted GPS antenna for my femtocell lost satellite visibility whenever the new TV was on.
@PoagMahone the hardest part is collating the two!
@hakluke Get a proper and fully shielded HDMI cable. The production cost of most HDMI and USB cables is barely more than a pack of Chinese noodles, so what did you expect? Engineering corners get cut below that fancy plastic molding, regardless the number of compliance stamps it carries.
@CobDetlef How do I know which ones are good? The prices don't seem to mean anything
@hakluke @SwiftOnSecurity More like a Highly Disruptive to Meetings Interface cable am I right
@mike_hasarms @SwiftOnSecurity eyyyyy 👈👈😎
@hakluke I had a 10m "Cat 8" LAN cable bought at Amazon, which would jam bluetooth and wlan in the neighbourhood. Nice.
@dothebart That actually sounds pretty awesome
@hakluke When the topic is about Electromagnetic interference ...
@5mukx hmm meowvelous
@hakluke HDMI quality cable are a shame to find. They are all called "4K" or so, but respect nothing. Put money in your cables, always, but not for gold on connectors : for shield and certification :)
@patrickbeau26 well i'm in the market for a good one, and amazon reviews don't seem to be much help, and prices on amazon don't seem to mean anything, so what's a good brand?
