Hotspot System / Router-Load Balance? Help please!

[moonseeker]

Hi all:

 

Urgent help needed. Existing system, "maintained" by local small tech-company. Basics:   20 Hotspots, mainly PICO Stations. 3 new D-Link 10/100/1000 switches total. 2 providers with 1000 & 400 MB accounts. Small IBM server with DayTek 2912 Vigor (which might be the problem!!!)   & IBSG 3.5 Software.

Lately, after adding few hotspots and higher speeds we are getting random problems with speed going to zero and drop-outs and other weird stuff like station won't connect etc.. Hard to define. We started with updating all firmware, upgrading switches etc. etc. Pings are good, even via WiFi. 

Just looked up the router-load balance , which is defined as small office network suitable. Jesus, should have double checked every step.....5555...

Any recommendation for a good router/load balance that is still affordable. Will also need 1 more 24 port switch, any ideas there? Stick with D-Link? Cisco etc. are far beyond our reach, unfortunately. Maybe somebody has some hints for a good website for general advanced networking, getting slowly the hang of it and think it is quite interesting. But am not very strong in math, formulas & physics, so pl. keep it basic for the old man. Ready to learn.

 

Thank you all very much.   MS>
