check grammar and fluency on this $"$In the past, I've had some issues with my router that messed up my internet. Sometimes, the internet would randomly cut out, making it hard to do stuff online. When this happened, I$\text{'}$d unplug the router for a bit and then plug it back in$.$ That usually fixed the problem, at least for a little while.

Another problem was when the internet was super slow, especially when lots of people were using it$.$ Streaming videos or downloading stuff took forever! To fix this, I called my internet company and they told me to change some settings on the router to make it work better. I also upgraded my internet plan to get faster speeds.

Sometimes, I worried about security too. I$\text{'}$d see weird stuff happening on my network, like devices I didn't recognize or suspicious activity. To make things safer, I$\text{'}$d update the router's software and make sure my Wi$-$Fi was locked down with a strong password. I also checked who was connected to my network regularly to make sure nobody sneaky was using it$.$

Overall, dealing with router problems can be annoying, but there are usually ways to fix them. With a bit of troubleshooting and some tweaks, I've been able to keep my internet working pretty well most of the time."
