<\/p>\nHello, everyone.<\/p>\n
This is Enta.<\/p>\n
<\/p>\n
My home internet connection suddenly got worse, so I replaced the wireless router.<\/p>\n
<\/p>\n
Wireless routers and LAN cable switching hubs are consumable items.<\/p>\n
It would be fine if I could use it until it breaks, but some kind of strange problem usually shows up first.<\/p>\n
It would be easier to understand if it couldn't be used all at once, lol.<\/p>\n
![\"Switching](\"https:\/\/norimen.net\/wordpress\/wp-content\/uploads\/2023\/01\/01.jpg\")
<\/p>\n
In our case, the connection has become quite unstable\u2014sometimes it works, sometimes it doesn't.<\/p>\n
So it took some time to isolate the problem.<\/p>\n
<\/p>\n
First, I replaced the wireless router, and while I was at it, I replaced the LAN cable as well.<\/p>\n
Since I was going to replace it anyway, I switched to a Cat 7 LAN cable.<\/p>\n
We also upgraded the switching hub to Cat 7 compatibility.<\/p>\n
Of course, the same goes for wireless routers.<\/p>\n
*Cat 7, Cat 6, and so on are types of LAN cable standards. The higher the number, the more stable the connection.<\/p>\n
<\/p>\n
Since the connection is still unstable, I'll check the devices connected to the fiber-optic line next.<\/p>\n
This device, called an ONU, is rented from NTT West, so there's nothing we can do about it.<\/p>\n
![\"ONU\"](\"https:\/\/norimen.net\/wordpress\/wp-content\/uploads\/2023\/01\/71j6QNDoqdL._AC_SY550_.jpg\")
<\/p>\n
For now, I'll try updating the firmware on this device to see what happens.<\/p>\n
Somehow, it seems like it'll be okay...<\/p>\n
I decided to just call NTT West for the time being and have them replace it, so I had them do the replacement and then checked the line.<\/p>\n
<\/p>\n
They said that since there were no issues with NTT's line and the ONU had been replaced, everything should be fine.<\/p>\n
It turned out the wireless router was broken after all\u2014which was a relief\u2014but it's still unstable!<\/p>\n
<\/p>\n
I've pretty much replaced everything, so I'm not really sure what's what anymore...<\/p>\n
We're now at the point where our only options are to inspect or replace the LAN cable inside the wall.<\/p>\n
<\/p>\n
I installed the LAN cables in the walls myself, so I set it up so I can easily replace them at any time.<\/p>\n
So, just as I was thinking, \"I guess I'll have to replace this part too,\" I looked over and\u2014!!!<\/p>\n
![\"LAN](\"https:\/\/norimen.net\/wordpress\/wp-content\/uploads\/2023\/01\/2023-01-23-00.08.28.jpg\")
<\/p>\n
This is it!<\/p>\n
It says \"Cat 6\" in the lower-left corner here!!<\/p>\n
It really reeks of the fact that it might not support Cat7, lol.<\/p>\n
<\/p>\n
I switched to Cat 7 thinking it would be faster and more stable overall, but I never realized this was the problem!<\/p>\n
That was a blind spot!!<\/p>\n
It's highly likely that the LAN modular jack isn't compatible!<\/p>\n
<\/p>\n
It appears that Cat7 is not yet a standard for general use.<\/p>\n
Looks like I was a little too early, lol.<\/p>\n
So, once I switched all the LAN cables back to Cat 6, the problem was pretty much solved!<\/p>\n
I've been dealing with this connection issue since the end of last year, so it's finally resolved... (It took about a month, lol)<\/p>\n

<\/p>\n
This time it had absolutely nothing to do with slopes, but it really made me realize that problems are usually right under our feet!<\/p>\n
As the saying goes, \u201cYou can\u2019t see what\u2019s right under your nose\u201d\u2014I really can\u2019t see what\u2019s right in front of me.<\/p>\n
<\/p>\n
We routinely perform slope stabilization and anchor installation work.<\/p>\n
Even though it may seem like business as usual, there might be a series of small issues building up that could lead to mistakes or accidents.<\/p>\n
We should probably focus more on the basics as we go about our daily work.<\/p>\n
As long as you have a clear view of what\u2019s right in front of you and a solid foundation, you can go as high as you want.<\/p>\n
<\/p>\n
Let's keep an eye on where we're stepping and stay safe today, too!<\/p>\n
<\/p>\n
See you later.<\/p>","protected":false},"excerpt":{"rendered":"
