The last time we had a problem with our wireless network, we finally got a new adapter from the repairman. We didn’t know where the problem was and we studied it there for a long time, but it didn’t work out very well. In fact, the adapter we bought before has been very useful for so many years without any problems, so we did not consider the problem of adapter at first, so we studied other aspects for a long time. It seems to be better to find a professional teacher, usually busy with work, so there has been no time to deal with this problem today because of vacation can be free to solve this problem.
