我在tl80的第一个月就开始了这篇科技911专栏，我得到了一个很好的答案，偶尔会有猜测，但大部分都是对你的许多科技问题进行了深入研究的意见。

继续发送任何和所有的技术问题，你有我的电子邮件地址或张贴在下面的评论他们，所以我有一大堆问题要解决2019年。同时，这里回顾一下tl80读者今年分享的一些最流行的技术难题。

如何处理来自你自己的垃圾邮件

I receive an overabundance of spam/junk email. Most, I block. However, the tricksters have found a way to send it, using my own email address as the return address. Since I can’t block my own email address, how can I find the true address they are being sent from, in order to block them?

为什么我的网络交换机不断下降千兆速度？

We recently upgraded our Comcast service to from 50 to 150 Mbps. That’s an important detail, because when I was checking the service from my Ethernet-connected desktop computer, I noticed I was only getting around 80–90 Mbps, not the 150–160 Mbps said landlord was finding on his tests. We repeated these tests across a number of days and times just to make sure there weren’t any weird network congestion issues affecting the speed results, and I c***istently found that I could never break past 100 Mbps, whereas he could on pretty much every test he ran.

为什么我的笔记本电脑会毁了我的wifi？

For several years now, my laptop (a refurbished 2016 Acer Aspire V-3) has been destroying my home internet soon after it connects to the router. Some times the internet crashes within seconds. Other times it takes days. But usually it is within 10 minutes.

为什么我从来没有搜索过的色情内容会出现在我的搜索历史中？

So, I’ll be honest, my boyfriend and I watch **** each separately on our phones. We each have gone through each others’ phone activity through Google, and when he looks at mine, there are items in there that I never Googled, like live cams chat room stuff. I have never in my life entered this into my Google search but I have a suspicion that they are pop ups from the **** sites. I want to know how and why they come up as my searches. And there are other things that show up that I supposedly googled but I know for a fact I didn’t.

为什么色情会神秘地出现在“新”iphone上？

When the thing was up & running, I opened Safari for some reason. (OK it was a few months ago, so I don’t quite remember the sequence; don’t think it auto opened.) The VERY FIRST thing it did without any action on my part was to connect to a **** site. I immediately deleted it.
