Hi,
I’m looking for some help to restore upload over ADSL.
I can download from the internet (via POP email, or using browser) but have lost upload capability.
If this works I’ll try and add system info, results from ifconfig and nmcli, &c.
thanks - JS

That can not be true. You can not download anything without being able to
send some packages to complete the connection, sending acks, etc.
It maybe that the speed is slower, but you have to prove that.

… later (it worked):
So not all upload function is lost (and I know that the ADSL connection is 2-way, from using another machine)
Pretty much everything about the problem machine is listed in (nope - can’t upload a file - maybe some edited highlights…)

how would I go about testing upload speed? I’ve tried Namesco speed test, which stalls at ‘preparing upload…’; my router info claims 864 kbps, which is about right, but untrue.

Try various speed test sites, if you have problems with many of them,
then it sounds like a problem your provider needs to be involved in
sorting out.

Several methods. You can use one of those pages that measure the adsl
speed, but it better be one on your ISP, that’s the easiest. Or, you can
upload a file somewhere and time it. But you have to make sure that nothing
else is using your network at the same time. If you have several machines
at home, unplug all but yours, and disable the Wi-Fi.

Hi, and thanks for your replies.
I’ve tried a couple of speed test sites and, like I mentioned before, they all stall on the upload test.
I know the router and broadband link are fine, as I can connect, send and receive email and otherwise do normal stuff on an alternative (WinXP) machine - as I could until last Thursday (26/1/12) on this machine.
I’m using Firefox 9.0.1 and Thunderbird 9.0, I experience the annoying Nepomuk triple ‘service failure’ warning pop-up bug, the mouse pointer control occasionally undergoes a go-slow for a minute at a time (usually once per session), and when my wife re-opens her account after switching-user she gets a ‘do you really want to disable keyboard?’ dialogue. Despite having specified nm-applet in ‘start-up’, KDE insists on using plasma widgets in the system tray (which are, admittedly, slightly improved in 4.7.4) - it was for a while showing a blank space (no nm-applet icon), which could be opened to reveal nm-applet, but now that’s gone.
I’m currently connected via wireless, but it makes no odds if I use ethernet.
I’d like to test email without Firefox (which results in a SMTP server timeout, after producing a % complete bar that depends on the size of the file: smaller file = higher %), but Kmail crashes with the ‘fails to fetch resource collection’ error (I’ve tried to set ‘local files’ in Akonadi resource configuration, but it doesn’t accept any folders I point it at) - so, is there a command line email tool?
I’ve tested FTP (Filezilla 3.5.1) and I can upload files smaller than ~1kB; anything larger fails.
Is there any other command-line system info I could retrieve that might help me discover where the network connection issue might be? I think it unlikely to be a hardware issue, more likely configuration, but I’m really stuck.
thanks - JS
I had a go at using the Filezilla network connection wizard:

there are a lot of mentions of ‘martian sources’, such as:
martian source 192.168.1.65 from 192.168.1.254, on dev wlan0
Feb 1 00:26:12 pavilion-linux kernel: [39665.065512] ll header: ff:ff:ff:ff:ff:ff:00:1b:5b:46:a0:f9:08:06
from my reading up this is nonsensical, as 192.168.1.65 is the ethernet address of this computer, and 192.168.1.254 is the router; the PC address is within the configured range of the router 192.168.1.64 - .253, so I’m not sure why it might be considered Martian…
I suggest 2 things… look at the sticky at the top of the network forum page and follow those directions (Yast search sysvinit-init install and delete systemd at the same time). I had I/O errors (as other have had) before switching this file. i couldn’t copy a few files onto a thumb drive. Reboot and check again. After that, I’d say take a look at your firewall. it could be blocking data to you box.
@surgie2: thanks - tried it, but alas, no improvement.
However, it turns out that changing MTU from 1500 (default) to 1400 (as recommended by very helpful TalkTalkBusiness tech support) has set the world to rights.
This was not straightforward, however, because BT2700HGV router firmware has javascript domain checking in configuration page; workaround is, instead of using ‘save’ button, to call up Firefox console (CTRL+SHIFT+K) and issue cmd: javascript:document.pagepost.submit() (as described here: Unlocking BT 2700HGV Business Hub (wireless router)).
Fixed!!!
and, because TTB tech support guy ‘re-synced our connection profile’ (I have no idea what this means!) whilst testing it, we now seem to have a ~30% increase in upload speed!
I have no idea how the issue arose: did the MTU setting change? unlikely; did something change at the exchange? who knows; how come the WinXP machine didn’t have a problem?

Are you sure the mask is correct?

@robin_listas: I’m pretty sure it is - there is now no martian presence in /var/log/messages.

That means that some broken machine in the way is not capable of doing
1500, and that tech support knows it.
