New Home Internet Connection Problems

For users with older laptops and wireless adapters that don't play well with the T-Mobile gateway and WI-FI6 - 802.11ax the best option is to just buy a USB adapter and upgrade that part. If the laptop is older and the vendor's support for the device is no longer available then the old drivers are all you have. 

When selecting a USB wireless network adapter please consider what you want and need. If you upgrade to an adapter with 802.11ax capabilities then you will be able to take advantage of the newer technology the gateway brings to the table. If you need to keep costs down a bit buy an 802.11ac adapter and you will still have pretty good performance. As you move backward your speeds will be reduced and the connectivity to the newer gateway radios may be a problem or more effort. If you run Linux vs Windows or Apple be sure the adapter has driver support for Linux. There are some with Realtec chips that work pretty well. My experience with ASUS adapters is they don't seem to have Linux driver support. Read the reviews carefully and decide on what you want. Fighting with an old adapter is more of a waste of time than just moving on with a newer wireless adapter.
