RE: [smartBridges] Strange problem?

Hi Jerry,   Using linear amps you will realize that you are increasing the output power level, at the same time noise also coming out from the device. As Tom Haynes mentioned, it reduces the sensitivity of the device as the Rx side gets multiple copies of packets due to the reflection and multipath interference.   Why we are not recommending any amps with our device means, there are some instances amps have been used with our radio and customers complaints about the performance degradation along with related problems like random disassociations and low throughput. As long as you didn’t experience above issues (degradation, intermittent disassociation and low throughput) then you may stick with the current installation setup.   The recovery utility will be able to search from the Ethernet side only and it is recommended also. Once used this utility, the device will go back to the AP mode (if already in CB mode) and we need to change back to CB mode and re-associate again.   Thank you and I appreciate your updates.   Kind regards, Seeni sB Tech Support   -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Jerry Carter Sent: Friday, November 28, 2003 2:07 PM To: [EMAIL PROTECTED] Subject: Re: [smartBridges] Strange problem?   Hello Senni,     I was originally thinking it may be the amp but then I thought why would a customer still be up and seemingly working fine 13 miles away if the amp was bad/defective? It almost seems to me that the firmware has gotten corrupted. Can I run the Recovery on a radio that is wired to another radio in client bridge mode or does it have to be taken down and logged into directly? And does running the recovery utility mean I am still going to have problems soon if it appears to fix the problem now?   I will update you in the morning on this (Midnight now:) )   Thank you, Jerry ----- Original Message ----- From: Seeni Mohamed To: [EMAIL PROTECTED] Sent: Thursday, November 27, 2003 10:52 PM Subject: RE: [smartBridges] Strange problem?   Hi Jerry,   Normally using an amplifier introduces noise in the radio and it reduces the sensitivity of the radio during transmit and receive. That is the reason we do not recommend any external amplifier on our devices. If possible, could you please try without using an amplifier? If you need very high power output then I would strongly recommend you to use high gain antenna with our devices.   Since you have already re-flashed the firmware, then I would suggest you to run this recovery utility to re flash the default configuration file back to the APPO. Please remember that using this utility will erase the configuration and please re-configure the APPO again. http://www.smartbridges.com/beta/utility/RecoveryUtility.exe   Once you have done, please update us on the status.   Thank you   Kind regards, Seeni sB Tech Support     -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Jerry Carter Sent: Friday, November 28, 2003 8:50 AM To: [EMAIL PROTECTED] Subject: [smartBridges] Strange problem?   We had a storm go thru today. Lasted about 15 minutes and had some lightning. Everyone went down until I noticed it (probly about 4 hours). I drove to the office and could get into the main app on the tower with simplemonitor. So I reset it and everyone started to connect back to it. Now it shows everyone with a 100% RSSI and Link Qualities from 0-82%. Now I can log into the customers airbridge and it shows great rssi and quality. I reflashed the app on the tower with the firmware wirelessly and it did not change anything. I do have an amp on this app. Is this something thats just gonna keep working and just not show right? Or is this radio on its way out? Or maybe the amp?   Thank you, Jerry
