E169 - New router - Billion 7404VGPX (speed issues)

Post by petemoss » Sat Jun 18, 2011 8:46 pm

Have been using the E169 on both Ubuntu and XP okay now for a year or two. Have had the occasional speed drop, but overall , it hasn't been too bad. It was used as a dongle, directly attached to the computer.

Now I have a new router, a Billion 7404VGPX and the speed is basically back to dialup. :(

Have checked the obvious setings, like APN is exetel1, MTU is 1500 I think. It connects okay and it working, but the speed is terrible since I started to use it. Any other settings I should check please ?

Pete, could it be that the back of the router is a lousy modem location? Perhaps try it on a USB extension cord to see if another spot, say a window sill, gives better signal strength (see 3G status).

Dazzled, the modem was always connected to an outside antenna, and so that factor hasn't changed.

In the config for the WAN connection, the settings are:

Mode: UMTS first
Tel No: *99***1#
APN: exetel1
Auth. Protocol: Chap (auto)
LCP Echo Period: every 10 seconds
MTU: 1500
Connection: Always On
Keep Alive: Enabled

is that the preferred MTU for 3G, it would be no good for ADSL, not sure how much overhead is involved in 3G though, I guess you could pull it down a bit and see if any change

I don't know what the MTU should be for 3G. Can't find any docs on the settings.

not sure either, taking it down a bit and comparing results is easy enough to try though

Seems MTU of 1492 is the value shown from this Whirlpool search

I tried that, saved config, rebooted, but no difference, still dialup speed.

Worth a try, but all my networked computers run at MTU=1500, and my gateway router which was once lower has been at 1500 without incident for a couple of years now. No change was made for those times when I've used a Huawei modem.

Thanks Dazzled. I had it at 1500, but speed still an issue. :(

I see one Billion whiz on Whirlpool suggests this to 'debug' ..
Login via consol, run the following commands & email logs, ensuring that issue is captured.

- system trace enable usb_host debug
- console enable
- ppp event 4
- event show
I think I just telnet in, from memory, rather than via a browser.

Pete

Edit later: Hmm, ... when I ran the above commands, nothing much, then ran the Exetel speed test, and it jumped up to 650.80kbps ?

worth doing a hard reset of the router and reconfig from scratch you think?

I have been doing many router restarts, which would no doubt equate to a hard reset.

This problem now appears to be more reception related, and possibly it is pure coincidence that the speed dropped when the new router was added. :?:

The speed actually picked up for some reason this afternoon, here are some results from Exetels speed test
2:24 pm Your current bandwidth reading is: 388.10kbps which means you can download at 48.51 KB/sec. from our servers.
2:26 pm Your current bandwidth reading is: 937.20kbps which means you can download at 117.15 KB/sec. from our servers.
2:44 pm Your current bandwidth reading is: 873.50kbps which means you can download at 109.19 KB/sec. from our servers.
2:51 pm Your current bandwidth reading is: 817.70kbps which means you can download at 102.21 KB/sec. from our servers.
5:16 pm Your current bandwidth reading is: 515.90kbps which means you can download at 64.49 KB/sec. from our servers
6:00 pm Your current bandwidth reading is: 593.60kbps which means you can download at 74.2 KB/sec. from our servers.
6:42 pm Your current bandwidth reading is: 624.40kbps which means you can download at 78.05 KB/sec. from our servers.
7:10 pm Your current bandwidth reading is: 242.80kbps which means you can download at 30.35 KB/sec. from our servers.
7:25 pm Your current bandwidth reading is: 785.30kbps which means you can download at 98.16 KB/sec. from our servers.
It has moments of no response and timeouts though, which is the nature of mobile broadband, but the speed has not been this slow for a long time.

When the speed picked up, I noticed it was very sunny, however it got very cloudy and the speed was the same, so seems sun/cloud have no bearing on reception. I may have to get someone out here and have a good look at it. We have a Yagi and I do want to use VoIP one day, and it would be nice to some degree of bandwidth consistency. :D
