Dsl Wireless connected but no internet

By maddogpop ·
We have a dsl wireless modem provided by our ISP that's being used in our boardroom for guests that continues to not connect to the internet but shows connected. After a reboot, it'll work but after "x" number hours, or maybe a day the same issue occurs. The lines has been tested with our ISP. Modem has been replaced also. Could it be because we may have too many connections and only allowed "x" number of leases. Also, from the modem, it also connects to a dlink switch to provide connectivity for computers. Any help is appreciated.

So have you tested the Power?

Most times things like this happen it's because the Power Line is dirty and has a lot of Hash/Spikes on it.

The ability to stop this is to clean up the Power Feed by filtering the Power, this is generally done with a Filtering UPS.

No I have not. I would have never thought of that. The modem is just connected to a regular power strip only. Any recommendation? So is it possible when rebooting the modem, it clears out these hash/spikes. Thank you for the suggestion.

Yep that's what happens when you reboot the Modem it clears the Damage tot he running OS done by the Spikes.

Typically Power Packs don't have any Filtering so they just knock the power down from Mains to the devices requirements this is a straight % step down and is a simple transformer so if you get a 1000 V Spike it gets knocked down to 100V or somewhere thereabouts. Ideally sticking some Capacitors in between the different Power Rails at the Design Stage will stop this happening but it costs money and after the device has been designed it's not possible to do.

A Filtering UPS will cure the problem or replacing the Plug Pack with a more stable Power Supply will have the same effect. If you have a UPS available I would try that first as it will tell you if it's going to cure the problem and if it does then you can source a decent Power Supply or just leave the UPS in place.

Make sure you have the proper DSL filters on any phone line where a phone may be attached
(unless the DSL line is specfically used only for DSL, meaning there are no analog phones attached to this DSL line)
