Well it looks more like a scan. But if this packet appear constantly and in the way you posted here, it can slow down your system. Because ARP processing has often a high cpu priority.

If the capture comes from a wireless interface of your PC, and your wireless AP's IP address (the most likely default gateway of your PC) is not 192.168.2.99, then someone is trying to map what machines exist in your wireless network and he has already cracked through your wireless security (if you don't use an open wireless network).
Else (i.e. if the capture comes from any interface of your PC, and regardless whether your router has 192.168.2.99 or not), the equipment which sends these arp requests is doing the scan, and it is likely one of your own ones which did not need to crack the wireless security. In a typical home network, a device doing that on a peaceful purpose is far less likely to exist than one infected with malware, so I'd be on high alert and would closely inspect the source device to find out what happens.
@Christian_R's suggestion that someone is scanning the network remotely would be fine if the address range in question would not be private (192.168.x.y/24). A scan over private addresses can not be done remotely over internet, it must come from a device for which such addresses are routable, i.e. inside your private network.
