When I first posted this thread, I mentioned in the end I had found a Windows laptop to try this out on a supported OS. After I got everything installed, the problem went away, on both the Linux host and the Windows host.
The problem has started again. I am seeing stalls of between 4 and 10 seconds, 5 times a minute, based on ping output. Sometimes the ping packets are just delayed, so I see a round-trip time of between 4 to 10 seconds, other times, I just get no response (packet loss). I have just had a 50 second and a 37 second stall as I write this message. This impacts my interactive ssh sessions, web browsing and VoIP.
I am also having multiple drop-outs each day, when the PPP session drops and needs to be re-established. Sometimes it takes a while (a few minutes) to re-establish, other times it re-establishes instantly.
When the stalls occur, the modem drops back to WCDMA from HSDPA. I have full signal strength (5 bars), and connected to the "YES OPTUS" network. I am situated in South Melbourne. The HSPA modem (E169) is stationary all day. I do not believe that this is caused by loss of signal. I have the Wireless Broadband application set to "WCDMA only" so it should not be falling back to GPRS.
I am currently stalled for over 5 minutes. It has not disconnected - the light is not flashing - it is solid dark blue.
I have been having these problems for the last week or so. Prior to that for the last couple of months I have had no problems. Currently the service is too poor to use effectively.
Would you please escalate this to your supplier? Or is there some other tests I need to do?
