If you mean a Cisco 2950, I guess you want to learn Networking. So a good place to start is to run GNS3 (https://gns3.com). You can download a VM image and run that, that's what I do. GNS3 is a great learning tool and you can use both real (your 2950) and virtual devices to make networks. Source: over 2 years ago

[dn42](https://dn42.eu/) also has, effectively, a playground for BGP. While I don't have experience with it personally, it seems to be just a VPN network with private addressing where you can find other folks to form neighbors with. That being said, you don't need to be online to play with routing protocols. A couple VMs with your favourite flavour of Cisco/Juniper virtualised switches do just as well.

As mentioned, Cisco, Juniper, Aruba, etc... All have certificates and training. You can use GNS3 on your own computer to learn networking, it's an industry standard tool. Source: almost 5 years ago
I can't guarantee any of this equipment will fix your issue with wifi. Any chance you can run CAT5/6 cable? If you want to learn networking without investing tons of money start learning to use GNS3. Source: almost 5 years ago
