Like an idiot i allowed my Neighbor use my wifi until i found hidden devices During an ARP scan. One day i had wireshark scanning when suddenly a new device connected to network and my time date changed. This was back about a month ago. This goes much deeper than that. I believe he had access for months at least thats what the router logs tell me. He denies it but im not stupid plus while he was away from his apartment his 2 devices were removed from my network when his Electricity suddenly went out. Plus i connected a new Wifi modem/router to my pc without any access to internet and his server or whatever hacked it in less than 5 minutes bombarding it with empty packets and malware. I cant keep this guy out. As soon as i get him out he will get back in when he realizes hes no longer online. My 10yr old sons tablet has system apps that dont belong which hes using to track whatever as well as my Pixel XL which is being replaced by google for one that i can root. I switched router 3 times now. Reinstalled windows and linux from a clean slate. Only thing i can think of is maybe he changed the iso files of windows n linux during the download. Help!!

Hi,

Scan your PC and other devices, re-create network, use strong passwords. Dont worry much about it, its problem that can be fixed.

Good luck

Yeah it is for some reason. I install windows or Linux and instantly shit gets changed as soon as i connect to network. Ive done everything i can think of. Here is a link to cloud shark that i uploaded from wireshark for what happened the day i got infected. Its more towards the bottom. If anyone knows how to read it let me know please.

If you try what 'ThumperTM' and 'AlexB121' suggested than you should be ok.
You could also try:
Reformat/reset (if you are confident enough) all of the devices that connect to your network like your main computer including any modem routers, routers, HDDs, SSDs USB drives, Navigation systems (like Garmin or TomTom) etc.
It is possible that a nasty virus/worm has jumped to all of your devices and keeps reinfecting your network or even your friends system and network and so on (possiply your neighbours, too).
I would start by disabling the wifi and turning off all devices (incl. tvs and printers), reset your modem router to factory settings and setup with new security settings. Connect only one clean and reformatted computer to your network at this stage and see what happens. If nothing bad happens than connect the next device and monitor the situation, and so on.

I'm sure everthing will be ok. :)

i hope you are ok now:).......almost 2 years later

And even 4 more years after your kind thoughts. Me too.

A router can be configured to only allow certain MAC addresses and disallow any others (white listing)... as well as one can "spoof" their MAC addresses... which Google will certainly provide these options with information.

Also, changing the WiFi password helps, among so many other simple methods to keep a hacker busier than a bee, and give up in frustration after a bit.

And in closing, I believe there is a way to make your router and IP invisible to the surrounding area. so you do not show up on their scans. (Hide My IP, etc.)

Google it.

1 - Unplug your router from electricity
2 - Plug a cable to the router
3 - Change wifi password
4 - Done

Yeah I suspect that was from the old days when wep encryption was the standard. Wi-Fi routers were easily hacked using an automated brute force attack. The trouble with Mac filtering is they can be spoofed easily these days. I guess back then you couldn’t have 2 tiered access (aka guest account limited privileges) on most home routers. I always wondered how his friend got admin access to the router. Oh well, old discussion.
