So if you need consistent you get wired. Here I see a bit of variation but my router firmware is current and I'm not running Torrents which get another sort of interference.
So i've come across this problem where out of nowhere my wifi connection goes to ****. It first happened last weeks wednesday i wasn't able to use internet at all. When i did a speed test the results were about 2 mbps download and 90 mbps upload. Before it was 90 on both. On the same week i contacted my isp and they send me guy to fix the problem but by the time he arrived on friday the problem has already fixed itself and speed was all good again. Now is the next week's tuesday and same thing is starting again. Only difference is that download has good speed and upload is the bad one. I'm getting really pissed about this because i have no idea what's causing this. If it helps - i bought a new D-link router about a month ago so maybe that could be the problem. Thanks for any kind of help.
