SonicWall TZ180 disabled upload! How to solve?

Last Modified: 2012-05-06
Hello,
we've got a new network at home. The structure starts with the actual router which is connected to a Sonicwall TZ180 hardware firewall which is again wirelessly connected to two access points / repeater over which I go online.

1.) When connected to one of the access points I can go online and surf the internet. However, there's no upload at all. I can't send any emails or upload files at all.

2.) When directly connected to the router via LAN cable, I don't have any difficulties at all to send or upload files, meaning that the problem must be the Sonicwall TZ180.

What needs to be done to change the settings in Sonicwall TZ180 to enable upload again?

Hi Patrick,

What subnet is the router's LAN on, and is this the same as the wireless subnet?

Also, do you have the same issue if you connect a laptop / pc directly to these mediums without the firewall?

Any specific reason why you have Sonicwall behind a router; what if you connect sonicwall directly to the modem and see results. Not sure, but double NAT sometimes can cause problems.

Thank you.

@ uk52rob:
I don't know what subnet the router is on. How can I figure that out?

What mediums are you talking about? As I already said, I directly connected my macbook to the router / modem via LAN cable and had no problems sending mails or uploading files to the internet. But I can't connect to the access points since they are sort of unreachable in our roof.

@dpk_wal:
No, there's no specific reason for having a Sonicwall. I can't tell you how much I cursed this stupid thing! I already tried unplugging the cable which was coming from the router / modem into the Sonicwall, and plug it directly into the splitter which splits the signal to both of the two repeater / access points. But it didn't work. I didn't get any signal / internet.

As I understand the setup you have:
modem---router---sonicwall---wireless access point1
                                              |-------wireless access point2

The access points are they acting as wireless to wired bridges; or they are are configured in NAT mode.

Details about the setup would help troubleshoot.

Thank you.

Hi dpk_wal,
Unfortunately, I'm not able to tell you that. However, if you want I could give you access to my computer via Teamviewer so that you could find out whatever you need to find out.

Or is there another way to figure that out?

Please tell about the model of the access points and the version of software they are currently running; would try reading the manual what setting they should have.

Thank you.

Hi dpk_wal,

The model of the access point is Cisco Systems - AP1242AG-E-K9. I can't access is for the following reason:

Sorry but I am not able to view the video.
I am not too conversant with Cisco products so would not be of much help here.
