Router Overload? Small office keeps dropping downloads

We have a small office with 25-30 devices connected to the network. Most of the devices are working constantly.

ISSUE: cant download/upload through Ethernet, website load times are slow, cant have more than 2 people on wi-fi, downloads from wi-fi work but not Ethernet.

We have a set up of.

          ------> Network Drive

Modem---->Router 

          ------> Switch -----> Ethernet

Our Router is DLINK 835. We also have a switch DGS-1024D both are new because of the issue(we thought either router or network switch died)

My thought is that its the router - there might be just too many connections in the office and its not fast enough to handle the load and we need to get a new Enterprise level router.

I also looked at the log of the router. It keeps posing the same lines in the log. I have no idea what they mean.

Do you guys have any ideas? Suggestions for gear? Suggestions for temporary fix?

It's weird that manufacturers will list the capacities of the MAC address table and packet buffer memory for Ethernet switches, but specs for wireless router units (which incorporate a switch) typically do not mention such capacities. It's almost like they are too embarrassed to reveal these capacities. Normally a manufacturer will tout every common & unique feature and numerical capacity if they think it's better than their competition's products or want to out-spec the competition in RFP bids. – sawdust – 2012-10-06T01:09:29.590

yes thats the one. I dont think its router`s fault - its not broken or anything, it just cant handle the load.

we basically looking for something bigger and stronger. Talked to Cisco Agent and he advised Cisco 1921 router – Kalvin Klien – 2012-10-05T23:35:53.850

do you have any recommendations on the router model from Cisco? – Kalvin Klien – 2012-10-05T23:37:14.613

PS: The Modem is not a Moder+Router combo – Kalvin Klien – 2012-10-05T23:37:58.293

Do you have a budget? You'll be dropping a thousand bucks on a 1921 series when you could probably get by with much less.

Ive used this guy with great success. Dual WAN, Gigabit ethernet and support for 50 VPN clients.

So our network guy came by and told us that those logs that I posted mean that the DNS servers of ISP went down and thats why our internet was acting up - not because of our router.

Thanks for replies! I'll definitely look into that router for next upgrade project. – Kalvin Klien – 2012-10-09T17:01:07.670
