when I brought the computer back to bestbuy we did a speed test and it was like nothing was wroung with the wireless adapter. My router is a Linksys AC1900 it shows connected in the wireless setting but the speeds are sloooooow
We understand you're experiencing slow download speeds while using your new laptop.
Since you were able to test your system in another network discarding our wireless adapter as the issue, we'll need to look into your router settings to figure out what's going on.
Please keep in mind you will need to contact Linksys* or your internet service provider (ISP) for support in this area. However, in the spirit of going the extra mile we can still make a few suggestions:
1. Make sure that your router is running the latest firmware.

2. Make sure that your new laptop isn't being de-prioritized by your router

3. If you're far away from your router or there are several walls between you, make sure to use the 2.4GHz band. If not, the 5GHz band is usually better.
If this still doesn't help, please run the https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility Intel® System Support Utility on that computer while connected to your home network. You will then need to use the "advanced editor" while replying to attach the report generated.
