Waykand, Just my 2 cents your also going to see problems with a cheap switch unless you can for sure get in and force it to 10 meg 1/2 duplex! the Airbridges don't play nice with switches that auto sense. I had to go out and buy a 12 port Cisco router that I could log into and set to the correct setting and if you go back there are many threads of people seeing problems with packet loss, slow throughput and many other problems all because an auto sensing D-link, Linkysys and many other cheap switches always sense the AB as 10 meg FULL duplex.
Anyone please correct me if I am wrong here? So anyways I have not had a chance to put this new Cisco up at the tower since I have to find a nema box big enough to fit this damn full size switch up there! I will post to let you all know if I see no more or less of the Single defer packet errors.. ----- Original Message ----- From: "Wayland Sothcott" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]>; "David Moss" <[EMAIL PROTECTED]> Sent: Friday, October 10, 2003 7:25 AM Subject: Re: [smartBridges] Local traffic swamping with hub (MRTG) Hello David, Ah! I wondered if it was doing that. So the wireless is acting just like a simple hub arangement, not like a switch which knows which port to send the data on. I will try replacing my hub with a cheap 10/100 switch and see what effect that has. These days the 10Mb hubs that used to be sold have been superseeded by 10/100 switches. As far as I know, these are smart enough to know which MAC addresses are on which socket. I don't want to go all out for a router as this requires configuration. Thanks for your help.
