Upgrading/Replacing WiMAX home gateway and slow upload speeds

This is going to be a two parter query.

I currently own a WiMAX home gateway which i purchased when i started my contract with VW on February 11 2011, which makes it 5 years and 19 weeks old plus whenever it was manufactured.

It has performed pretty well all these years, but lately in the last few weeks it has started to constantly lose power and reset itself. Ive gone through the basics of changing power points in the house and power boards to see if it works any better but it doesnt help.

So i am wondering what my options are. Is it as simple as just purchasing a new home gateway, or even a new LTE modem and remain on my current plan without needing to change anything?


EDIT 6:20pm - It seems to have mostly corrected itself for the time being and i am back to the usual 35KB/s http://www.speedtest.net/result/5427697206.png

For the last 2 days my upload speeds have been consistently below 10KB/s making gaming all but impossible. I dont know if this is related to the power issue or not, since i've had pretty reliable speeds before that even with the resets. I'm in the Waterloo area of Sydney and have seen a few network outage posts for a few surrounding areas and was wondering if that could have anything to do with it.

Here's a speedtest from not long ago. The d/l is about 50% slower than normal at this time of day and the u/l is pretty horrendous. http://www.speedtest.net/result/5427421224.png

I am connected to the same tower i always am, and the router hasn't been moved for years and i cant think of anything on my end that has changed.

(1) regarding replacement of the WiMAX modem, I wouldn't necessarily recommend purchasing a new one ... but it might be worthwhile calling vividwireless and asking them whether they have any unwanted spares and maybe they could replace it for you? Reason I suggest that is that the future is LTE not WiMAX, so try to avoid throwing any $$$ at the problem if you can. You might also take the opportunity to ask them whether there is a free upgrade path for you to get to LTE ?

(2) regarding the Upload issue, it is hard to say for sure without analysis, however your two ideas about it being Outage-related or being ModemFault-related seem on the money. If your modem is struggling anyway, then I would lean towards the modem being the cause. Upload relies on the modem transmitting and if something is failing in the modem then it might not have enough oomph to get the packets safely to the tower.

It would still be worthwhile spending 10-15 minutes with the modem and a long extension cord, to see whether moving it will make a difference. Vividwireless have been making a lot of network changes in recent months, so maybe your signal is coming from a different tower now?

What are your CINR and RSSI numbers from the modem?

Alright, I'll give them a call and see what they suggest about the modem tomorrow.

Yeah i have tried moving it around but the only other tower near me is much worse than the one im on now so that doesnt help much.

My normal tower gives me CINR/RSSI numbers of 23/21 64dBm at the top end and 18/16 70dBm at the bottom and i fluctuate in between. I get max download speeds of 1.1 MB/s - 1.3 MB/s so thats never been an issue before. Currently both numbers are jumping all over the place, and i'm getting some packet loss every now again as well which seems to coincide with an entry in the log called "NETDEV WATCHDOG: wmx0: transmit timed out". that can last for up to a few minutes.

That particular log entry has been observed by a number of people. Are you on the latest 1.4.4 firmware? That signal is quite good quality at the top end. The 18/16 is more of an issue. Sounds like it might be dropping its connection to the tower.

Have you checked to see whether you are in coverage for the new LTE modems?

I'm on firmware version 2.8.8 - 1.4.4. I've been getting those messages for at least the last 2 years, or at least thats when i started paying attention to the logs. When the signal gets that low its usually only for a few seconds then bounces back up again, but i've never it seen stay at any number for more than a few seconds at a time anyway even when its "stable" around the 20's.

I couldnt find a coverage map on the website anymore, but after putting in my address it said i was covered by LTE.
