So recently our company has purchased a Cisco C881. I've loaded CP Express on it just in case because I'm still learning to work with the CLI. I've configured a static WAN interface (fixed speed at 100Mbps Full Duplex) just like on our old router. Static DNS, IP etc. While I am able to access the internet, it is incredibly slow for some reason. And not all sites, twitter.com opens up just like that. While Google takes it sweet time and sometimes does not open at all. Most of the websites do this.
I tried pinging websites from the router (like Google) and get 40% and 60% most, a lot of packets are being dropped. On CP Expres I opened pretty much everything from LAN to WAN. Is there a config. that I'm possibly missing that is causing this? Tried putting a switch between the Cisco router and my laptop but the problem still remains.
Current configuration : 13471 bytes

There are likely two default routes with the same administrative distance that are both being used equally (load balanced).
Except one of your routes (ip route 0.0.0.0 0.0.0.0 FastEthernet4) is not going to work because you specified an interface which means it's going to ARP for every destination IP, thinking it's directly connected and then fail. Plus, even if it did work, that's unnecessary, so you should definitely remove that route either way.
I've deleted the fastethernet 4 route like you said. The one with: 0.0.0.0 0.0.0.0 [ISP default gateway] is still enable though, should I delete that one as well? Still unclear on what this exactly does?
I put in the show ip route and got the following result:
Router#sh ip route Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2 i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2 ia - IS-IS inter area, * - candidate default, U - per-user static route o - ODR, P - periodic downloaded static route, H - NHRP, l - LISP a - application route + - replicated route, % - next hop override, p - overrides from PfR
Gateway of last resort is not set
192.168.1.0/24 is variably subnetted, 2 subnets, 2 masks C 192.168.1.0/24 is directly connected, Vlan1 L 192.168.1.1/32 is directly connected, Vlan1
I'm assuming this is how it should look like. Currently my laptop is the only device connected to the router, can't connect the router to the modem until tomorrow. Once I get the results, I'll post them here. But should it look something like the output above?
I also deleted all the 'match' protocols, from what I understand that takes up a fair share of resources as well.
Leave the other route there - you need it. It's what is telling your router what to do with traffic destined for the Internet.
The one you deleted was a misconfigured route that was the likely cause of your router dropping half the packets.
When you connect the modem, your routing table will also include an S (static) route to 0.0.0.0. Just test and see how it goes. You should not be dropping half your packets now unless I'm missing something else.
