his is my computer - everyone around me is doing fine on internet (we have Wifi)
Is there something that I can do to try and speed mine up?

Those numbers are pretty terrible. There can be many causes for that. The most common is a poor connection to the wifi router. If you have more than one router in your home/office, if the computer is not making the move from one to the other as you move through the location, that can result is numbers like this. There are ways to determine how strong the signal is in a specific location. Another reason can obviously be that the actual signal provided by the ISP is the problem. That can absolutely be the reason but usually the numbers wouldn’t be that low. It’s more likely that your connection to your router is the problem.

It’s also possible that your wifi card has become disconnected or has failed. These modules are very small and usually have a very small cable antenna attached via a snap mechanism. If the antenna has become separated that would cause the super low signal as well. That would require Apple to do the hardware require.
