Why are my devices no longer connecting? (Before I try to reset)

[Iphoner]

Ive changed nothing in my set up for like the past 2 years or more since I had my Netgear Wifi set up. Last week my girlfriends Ipod was no longer able to connect to my signal, but I was. So this week I decide to take a look at why her ipod was no longer connecting to my wifi, and then bam, now MY iphone is no longer able to join in my signal.

I dont see any solution to this posted. The router is still transmitting a signal, just now our devices are unable to join it. How do i fix that? Why was her device the first to do this, while mine stayed connected? How do I get back on to my signal? Ive even turned the password off and still no good.

Time to hard reset the router and reconfigure it from scratch.

two possibilities. Channel interference issues that causing "IF" surrounding has changed with more wifi signals...

or

resetting the router will be your choice.

for iphone/ipad, click on blue > next the SSID name under setting's wifi and use forget this network options

try again reconnect is one other thing you can do but if there is no significant changes in surrounding that you think it is not channel interference issues then reset the router

Lot of reasons. Here are 3 possibilities.
1. Most likely, one of your neighbors close-by has installed his/her own wifi network, which caused signal interference to your wifi network.
Solution: change your channel to a different one from your neighbor's

2. Two years passed, if you have never change your SSID password, that's a lot of time for hacker(s) to hack into your wifi and steal your bandwidth.
Solution: time to change your SSID password, as well as your router's admin password.

3. May be the unit just need some maintenance, physically and logically. May be it's dusty sitting there for 2 years and need to be undusted. May be it's memory's going corrupted running for 2 years non-stop, need to give it a clean start again by doing a hard reset on the router. Better maintain it now, before it really goes bad.

That’s not how 802.11 operates, look up CSMA/CA. If a neighbouring network had that kind of effect wireless networking in general would be doomed to failure, in my case I have up to 26 in-range networks operating at times, typically at least 15.

It seems too coincidental that as soon as a change was made to the router settings, the phone that was able to connect is no longer able to do so, and without knowing what that change was then a re-configure may be the best option.
