Why is the wifi adapter not working?

Question

Iron

I purchased a PCI-E wifi adapter from Tp-link. Problem: the column began to make noise, and it works very slowly and with breaks, the driver installed

Answer 1

What the heck PCI-E? better go and exchange it for a simple usb, they are smart, small and mobile)
Well, if you don’t want to change, then the point is the connection .. The quality is bad and due to the fact that it is “narrower than necessary”, a space is created that interferes ..
Here is a simple way to check, you take out the adapter, if the noise is gone in the speakers, then go change it or shove it into another PCI-E. But I think that this is not PCI-E loosened .. it's in the adapter, I won't say anything more precisely, only assumptions.
If something like this happens, then it's not about the draws: D
I can even advise a model, it costs within 800r and holds up to 300mb / sec normally. signal strength 15dbi

Answer 2

The speakers may not have a good quality audio cable (bad screen). This can be checked by holding a mobile phone close to it during a call. It is solved by replacing the speakers with better ones.
Working with discontinuities is not surprising, the adapter antenna should preferably be placed higher and away from clusters of wires, metal objects, etc. It is solved by using a remote antenna on an extension cable (if the native antenna is removable) or by replacing it with a USB adapter placed on a USB cable.

Answer 3

MySQL is just one of the fastest solutions in this area.
Because SIMPLE (you can still tinker with the settings of MySQL itself - MyISAM is faster than InnoDB)
PostgreSQL is not faster. But trickier. When you need, for example, something more powerful in terms of transactions or clustering / replication - then look at PostgreSQL. The transition from MySQL to PostgreSQL is not elementary, especially if you need PostgreSQL features that MySQL has no analogues from the very beginning.
MariaDB is the same MySQL only more brought to mind. Moving from MySQL to it is elementary (almost nothing needs to be changed).
If everything suits, then MariaDB still makes sense. And it's simple.
And PostgreSQL - here you need to understand why you need it. And there's a lot more work to do there.

Answer 4

Actually the main question - why? what for to you to change a DBMS? what are the reasons for this? If you are quite satisfied with the functionality of MySQL, if your database can handle the load, then you do not need to do unnecessary work that no one needs.
At the expense of problems when moving from one database to another - here no one will tell you for sure whether there will be problems or not, because. it is not known what the specifics of the project are, how it is organized, how independent it is from the base, etc.
In any case, before making a decision to transfer the project to another DBMS or not, you need to understand all the PLUSES of the translation and all the MINUSES, and comprehensively evaluate whether the game is a candle or not. As for me, postgresql is better than mysql in many ways, but if there are no obvious reasons to change the DBMS, you should not do it
