That is a really dated model, in its day a mediocre but usable tablet but in today's tech environment you need to really set your expectations a lot lower. Google stopped supporting it long ago so not only is the Android operating system really out of date, any apps you can manipulate and install will also be woefully outdated as independent developers rarely provide apps for Gingerbread now. On top of basic software issues, there are hardware limitations that can't be ignored either -- old processor CPU and GPU, below spec amount of RAM, very low amount of storage space, display resolution that can't cope with current web technology, it's battery is old too so general usage won't be too impressive at all and charging times increased, among all kinds of other issues.
Really, online interactions will be a problem as current web services have continued to advance past this tablet's capabilities. So you can keep trying to get this tablet to do things it just isn't able to do, or upgrade to a new or newer one that will just work as is.
