To be honest: No.
It's 9:20 pm at mine, I have an music exeam tomorrow and need to get up before 5 am.
So I'll try to open my gate .. I already know this won't work -.-
Usually my wifi works perfectly -.-
There are just some days where I have to wait until the next comes and then it works again like before. It also appears that I just need to wait a few hours.
If my wifi is bad it will stay bad 3 - 5 - 48 hours. I hate it.
Graphs of linear functions ;_; Im really stuck on it D: Its my tuition hw and they go really fast. Everyone else grabs it quickly and I get really confused D;
