Our small store has for years put up an open unencrypted wireless router with the SSID
storename-public, as a community service, with the 'public' in the SSID so that users would know not to transmit sensitive info across it.
Recently we noticed a dramatic slowdown and realized someone nearby has put up an extender with the SSID
We have several problems with this:
- The first being of course the impact on our own throughput.
- Another problem is the possibility that they are actually capturing private info and we will get the bad rep.
- The third problem is the simple fact that they are using our network in an unauthorised manner.
We'd like to keep the open wireless up. Is there a way to block the extender without requiring passwords on our own router? What would be the effect of changing our SSID to something 32 chars long; would that stymie their extender? The extender apparently clones our own MAC address so I can't block that.
