Solution for slow and unstable wi-fi speeds.
A customer in Korimoto, Ichihara, Chiba Prefecture, requested that we improve the Wi-fi speed because it is sometimes slow and the connection is unstable.
Carrier.
The contracted line provider is Nuro Hikari.
Nuro hikari is characterized by the use of high-spec routers, which are also provided by Nuro.
preliminary investigation.
We conducted a preliminary survey with the cooperation of our customers.
There is a website called “fast” that allows you to measure the speed of your Internet connection for free.
We asked the customer to measure the current status on this site.
After taking several measurements, we found that the speeds ranged from 6.5Mbps to 670Kbps, which was quite unstable and slow.
Since Nuro Hikari should be able to provide more than 100 Mbps, we decided to visit the site and investigate the cause of the problem.
Site
It was a two-story house.
Wi-fi Diagnostics
We arrived at the customer’s home and immediately performed a wi-fi diagnosis.
We checked the Wi-fi speed of the router and found that it was producing over 100 Mbps, indicating that there was no problem.
Next, we checked the settings of the customer’s phone and found that it was connected to a signal in the 2.4GHz frequency band.
This seemed to be the cause of the slow connection speed.
The 2.4 GHz frequency is easily affected by household appliances (especially microwave ovens) and airplane radios, which can cause problems with radio interference, resulting in unstable or slow Internet speeds.
For this reason, we have changed the settings to always connect to 5.0 GHz.
We connected to Wi-fi in the 5.0GHz frequency band and measured the network line speed again with FAST, and found that it was over 100Mbps without any problem, and we were able to solve the problem.
Thank you very much for your request.

He seemed to be having trouble with poor cell phone reception, so we conducted a detailed hearing.
The phone is Rakuten Mobile, and the signal at home seems to be weak all the time.
We informed him that Rakuten Mobile allows you to “request an investigation to improve the signal”.
We told them that our office and conference room also had a weak signal and that we had requested Rakuten Mobile to improve the signal in the past, and the problem was solved within a few weeks.
