Network connectivity problem

[acobo]

Hello all,
My Dreambox 7000S is not able to connect to Internet, and after a lot of tests, I don’t know what else to try, any help will be very appreciated.
The problem is that it seems not to be connected at all: I cannot download keys, addons or softcams (I get “download failed” or the DB hangs) ; Links web-browser only shows a blank page, the Weather plugin says: “timeout, data not available”, etc. However, I have tried to connect the DB to the LAN of my workplace, and everything works OK!
I have a small LAN at home, with three computers with Windows and the Dreambox. The connection WITHIN the home network is OK: I can access the Dreambox with Dreambox Control Center, by Telnet, FTP, HTPP, upload new images, ... everything works fine, so it seems a problem with the Internet access, routing, or something related.
BUT, I have done the following tests:
-I have tried to access the DB from my workplace to my home, using Telnet, FTP and HTPP, at it works always (I can see the HTTP page, transfer files by FTP, do a Telnet session, …)
-I can do Telnet from my dreambox to any external server in Internet, also, without problems.
-pings to the other computers inside the home network are OK, but pings to the ADSL router or computers beyond result in duplicated echoes (sometimes, up to 40% of the packets are duplicated, other a few percent, but I always get duplicated echoes).

I think that the problem come from the wireless bridge (802.11b) located between my wired home network and the ADSL router (and hence, the Internet), which is only 50meters long. I am using two “paired” access points from USRobotics, one as an access point and the other as a wireless client. The weird thing is that I haven’t notice any problem in two years with this wireless bridge, before having the Dreambox. All network services (pings, web browsing, …) in the three computers are running OK.

It seems that the problem is due to a particular way that the Linux box do the networking (all other computers are running WinXP or Win98), but I am not a expert in Linux.
I have look to ifconfig for errors, but I get always the same: (BTW, TX and RX bytes is always zero, is it ok?)

/tmp > ifconfig
eth0 Link encap:Ethernet HWaddr 00:09:34:10:1E:34

Interrupt:28 Base address:0xa300 DMA chan:ff

While looking to netstat when trying to download something, the TCP connection stays as “ESTABLISH” forever:

/tmp > netstat -n

I’m sorry for the long explanation. Any help will be welcome!
Thanks in advance,
Adolfo.

i have the same network with xp machines and dreambox 7000, and a similar problem when i use aol and avirt (avirt is needed because aol is not xp compliant) to connect the internet.... if i use an other ISP like free (compatible XP) it works.

Thanks Mike72 for your reply.
However, It is not easy to change of ISP with ADSL connection, there are a few available here and you have to keep the contract for one or two years at least...
Anyway, I don't think that this is a problem related to the ISP. Looking deeper into it, I have discovered that all downloads performed by Dreambox Images (I am using Hydra Lucien at the moment, but it is the same with others, I think) are based on the "wget" command, that is, they do a HTTP get method to retrieve a file. I have copied some of the URLs (for keys, softcams and addons) and try to do the same with the IExplorer on the windows machines, and allways works! The dreambox, meanwhile, get frozen downloading forever with the same URL.
But i have tried to retrieve files from some others URLs with the same "wget" command in a telnet session, and SOMETIMES it works for SOME URLs!!
This problem is driving me crazy!!!
