Hey there, sorry to hear your internet’s acting up after that accidental RJ11 plug-in—let’s go through some practical steps to try fixing those pins 1 and 8!

First, let’s cover the prep and safety stuff:

• Always start by powering off your modem/router completely—unplug it from the wall to avoid any risk of electrical damage or shock while you work.
• Grab a few simple tools: a straightened paperclip, a thin toothpick (make sure it’s not too thick), and a small flashlight to get a clear view inside the RJ45 socket.

Here’s the step-by-step fix process:

• Use the flashlight to shine into the RJ45 socket. You should be able to see if pins 1 and 8 are pushed down below the level of the other pins (this is the common issue from RJ11 misplugs).
• Gently insert the straightened paperclip or toothpick under the bent pin, and slowly lift it back up to match the height of the adjacent pins. Take it slow—you don’t want to break the pin entirely!
• Once you’ve adjusted the pins, grab a working RJ45 connector (like the end of a spare Ethernet cable) and gently plug it into the socket a few times. This helps seat the pins back into their proper positions and tests if they can make contact correctly.
• Plug your modem/router back in, connect your Ethernet cable, and check if your internet performance is back to normal.

If you can’t get the pins to stay in place, or if you notice a pin is broken, you might need to replace the RJ45 socket itself. For that, you can either look up a replacement guide for your specific modem/router model, reach out to the manufacturer’s support, or take it to a local electronics repair shop.
