Still connected but only able to access Cell C website

[ginggs]

This happened to me again during the night. According to my router logs I had been connected since 09:02 on 2010/11/09. When I tried to use the internet this morning I could only access www.cellc.co.za, trying to access mybroadband.co.za and www.google.co.za timed out.

I started with a traceroute to mybroadband.co.za, which was successful:

This made me think the problem may lie with Cell-C's transparent web proxy, so I tried this:

$ tcptraceroute www.cellc.co.za 80
Selected device eth0, address 192.168.88.4, port 37853 for outgoing packets

 4  10.228.221.42  60.069 ms  69.799 ms  59.967 ms
 5  * * *

and this:

$ tcptraceroute mybroadband.co.za 80
Selected device eth0, address 192.168.88.4, port 37388 for outgoing packets
Tracing the path to mybroadband.co.za (41.203.21.137) on TCP port 80 (www), 30 hops max

 4  41.48.23.14  59.850 ms * *
 5  * * *

Notice the difference at hop 4. Is 41.48.23.14 Cell-C's proxy? It doesn't have a PTR record in DNS.

I then tried pinging and found that only the first ping was going through:

$ ping mybroadband.co.za

I disconnected and reconnected and everything was back to normal.

Update: I can connect to the Cell C website on "whoosh". But no other site.
@sajunky, I will try that now.

That any help?

Been having this problem again since wednesday, really pissing me off now.
Never had any response from cellc after there call on 5/6th.
Up till now cellc has been good, but this problem makes me use 50-60MB a day extra with the constant reconnecting.

[furnic]

sigh, well after 4 days after quite fast internet, this morning it connects and...nada, nothing, no internet, no email, not even the cell c website.
Will go for a drive to check if it connects elsewhere

[ginggs]

This has just happened again to me. Using an E1820 plugged into PC running Windows XP.
I had used about 180MB of traffic during the session, suddenly I could only browse to the www.cellc.co.za, and I couldn't ping www.google.co.za, mybroadband.co.za or www.cellc.co.za.

I thought I had finished my bundle, but *101# said I had 1.36MB remaining.
I disconnected and reconnected and was able to make this post.

And again. *101# says I have 0.44MB remanining, but when I connect now I can only browse to www.cellc.co.za.

I have been having the same problem today. Everything worked fine last night, but today I could only view the cell c website, which did not have any news of outages in the jhb area. I have almost 2GB left on my bundle.
Someone from cell c please pm me a solution, or notify us about the jhb / Killarney outage

[Dre21]

Same problem here, says im connected but cant browse... I eventually got so fed up (after trying to get something done since last week) i sat in Cell C's head office and demanded a technician come to my house and see what the problem is. They checked everything and they cant see the problem but say my signal isn't very good and that could be the reason, so they sending me a external antenna (no cost) and are going to be putting it up this week when it arrives.

They will point it directly at the closest tower and they say i should have fast STABLE (most important to me) connection.. So when they have done this i will tell you guys if it worked if not then, well i don't know take it back i suppose? what else can i do if even they cant fix it.

[Tun@]

Be great to see if it solves it or not - what OS & antivirus you using?

Doesn't make sense to me. How is the Cell-C website getting to you if your signal is that bad?

It's just happened to me on my phone now, the first thing I noticed was my Google Talk client went offline, I tried to go to mybroadband.co.za but couldn't, www.cellc.co.za still worked though.

Want to try see if this does anything

To do this, follow these steps:

Click Start, and in Start Search, type cmd.
Right-click the cmd entry that appears in the search results, and then click Run as administrator. If you are prompted for an administrator password or for a confirmation, type the password, or click Continue.
At the command prompt, type the following, and then press ENTER:
netsh winsock reset
Then, you should see the following message:
Successfully reset the Winsock Catalog. You must restart the computer in order to complete the reset.
Restart the computer.

Note If you receive an “Access Denied” error message instead of the message that is mentioned in step 3, the command prompt was not correctly elevated. In this case, close the Command Prompt window, and repeat steps 1 through 3. Make sure that you correctly implement step 2.

OK - what about this one then
http://support.microsoft.com/kb/299357
follow "Use a manual method to reset TCP/IP"

if that don't work maybe a closer look at that ipconfig - seems you got connection but no web page loading

In C:/Program files(x86)/Cell C/Driver/
Open the "release notes.txt" file & scroll to the bottom does the last entry say "Version 4.17.00.00" ?

Has your PC EVER had Norton AV on it (maybe when new,had a trial version installed?)
