Router Issues with Small Business

Hi all,

I am looking for advice on a router for a small business. Let me begin by explaining that the shop I work in has never had a dedicated IT person and is approx. 7000 sq. ft. I am trying my best to correct an issue that we have had for a while with losing connection to our router.

The current router is a bt business hub 3 which after reading many forums is not the best piece of kit! I have had an engineer round to test the line and can find no fault. The problem is we just lose connection to the router "dns server not responding" and have to constantly re-set it. We have tills, stock systems, repair systems and card machines all requiring the internet so having to re-set this connection constantly is obviously not good for customer service.

The majority of devices are wired via cat 5 sockets around the building:

5 x Till Processors (Windows 7)
6 x Office pcs (Windows 7)
4 x card processing terminals
1 x sonos music system

The cat 5 sockets all lead up into the ceiling and then into a central unit in our office upstairs using an HP 1810-48G switch to connect all to the router.

We have an access point at the back of the shop where there is a café for wifi access and also a range extender for wifi at the front as the router's range does not cover the whole 7000 sq.ft. I have recently switched off the access point and this has dropped the wifi devices to one phone and one tablet and this has not made a bit of difference to the internet drop outs!

It has been suggested that we should take on a secondary broadband line for the café wifi and leave all the wired devices on the first line but I cant help worrying that this will not solve the underlying issue of the router not being able to cope.

Any recommendations for a router to suit a large number of devices would be much appreciated.

Many thanks in advance :)

As far as the numbers of devices are not in hundreds or even thousands this is almost irrelevant to router capacity. In fact all home grade routers should be able to handle at least a range of C class subnet which is 255 devices (router included).

This error you are describing..."dns server not responding" is shown by a browser?
Did you try to ping the router address in the meantime to be sure its really router issue?
Routers aren't really a DNS servers, they can either set DNS settings on some machine over DHCP or rather be DNS proxy thus it might not be router side issue.

First step i would do is pinging both router and some external ip adress from any station in the network for continuous period of time (until you get the issue...

If ping shows packet drop from the station to both addresses then obviously routers had a hang (or switch hang?).
If ping shows packet drop from station only to external adress then it can also be line unstabilty (ISP issue).
If ping shows non drop whatsoever during the issue, its DNS resolving issue...

To make this test you either use build in windows command (using CMD console):
ping -t 192.168.1.1 - or whatever the router address is in your network
ping -t www.google.com

for more sophisticated analysis you could use software like this: http://www.pingplotter.com/

This doesn't really answer your question but it might be possible to solve it without throwing money away since it might be not a hardware issue.

Hi,

I get the warning triangle in the network icon on my pc and the webpage will fail to load. If you run the network diagnostics that is where it says the "dns server is not responding". I have had steady connection now for just over 4 hours but some days it loses connection two or three times every hour! Can I just check - you suggest I ping the router and websites until it loses connection or wait until it has lost connection and then post the results?

Many thanks for your help
