Hi there im new to the forums and before i carry on i just want to ask you guys to please excuse my spelling as ive neva been any good at it :D

Ok firstly iv'e been doing IT for many years now about 10 or so hardware/software and also dsl
installations, reason im saying this is to just get the basic trouble shooting attempts out the way.

Right, so i use to have a 384k dsl line a few months back and had it cut up and till 3 weeks ago.
Iv'e upgraded to a 4Mbps with a different ISP as im very anti telkom. Now when it was a 384k line i had my fair share of problems but it worked most of the time. Now every day between 3-5pm and 10-11pm it just busts out!?! I can ping web sites but has packet loss and also i cant browse th the web site all though sometimes IE does say web site found. The DSL and internet light is on. Telkom says they can see the router connected to the line and my ISP says they see my account is active but there is no data moving. Ive confirmed its not the ISP as if i enter telkoms guest account into the router i can not browse telkoms web site nor can i browse SAIX.
I have tried every to what i know anyways and been on the phone with telkom for many many days :cry: <--- very uncool. I just cant wrap my head around this problem and its almost as if someone else is connecting between these hours and cause interferance for me.

Please help as im paying for nothing.. i work standard hours 8-5 but at 5 my net is down.

Any ideas?:confused:
 
Is the line dedicated to the modem, or do you have a phone on it as well?
Have you tried with a different modem?
Have tried with a different network card?
Have you done a tracert when this happens, and what did you see?
 
Its possible that your routers DNS cache is corrupted. It used to happen to me all the time until I got a new one. Aparently bad register in RAM. just a suggestion.
 
The line has a phone connected to it but it never gets used even if i unplug it still the same thing. I havent tried another modem as i cant get my hands on one just for testing but think i should ask my boss to lone me one it might be worth a shot. But it doesnt make sense why these hours only and there is no parental settings on it to block it. the standard time it stops working is 5-10pm yesterday it stopped at 3. Not a network card as there are 3 pc's connected to it and local lan is always 100% fine. not sure how to do a tracert? Could you maybe tell me how?

Many thanks for the reply
 
hey. with telkom anything is possible. : )

windows command prompt --> tracert www.google.co.za --> check the hops. see if its breaking somewhere upstream.
 
Ok bleh69 i read your other posts and you seem pretty clued up. Thanks alot for the help. Ill run the test tonight and post results here. Lol and yea i guess it is true about telkom anything is possible but not in a good way :P
 
I really doubt that it would be DNS issues, since DNS problems won't prevent the ping packets from being sent incorrectly once the first packet was sent. ping queries the DNS and then tries to send icmp packets to the IP address, so its not doing any more DNS queries for the following icmp packets.

Doing a trace route (with tracert) is a good idea, not only for seeing how the network is routed, but also where the latency is experiencing big jumps.
 
Well i did the tracert test and it appears to be having problems at different hops each time i run the test. The strange thing is it use to be between 5-10pm as i said above but for the past 2 days its down to 5pm - 7:30pm. So it works earlyer but its the same problem, also i have to do a power cycle on the router before it works. Do you think this is a problem that will resolve it self? I hounestly cant see how this is a router problem.

Sounds like you router is screwed? Also ask your isp to reset your port

I dont know why everybody thinks its a router problem :confused:. I know for a fact its not the router but just to eliminate the factor ive tried another router with the exact same results. Ive had about 5 techies come over who knows for what because each one says the problem is not on site. So after a month heading to 2 months ive finally convinced telkom to switch my port on there exchange. I belive this is the last option i have, other wise dsl is not a option for me :mad:. Been getting alot of calls from telkom lately as ive become fed up with this and fighting with the poor desktop support parrots.
Thing that got to me for each time i logged a call it got marked as resoveled with out anything actually been done. Will let you guys know if the port swapping helps.
 
Phone Telkom ADSL helpdesk.

Ask for a specialist.

Give them your circuit number ie area code + phone number.
1. Ask them to delete the ADSL profile from your account and then re-create it.

Once that is done and the technician confirms this then check your connectivity again.

Whether or not your connectivity works as the problem could lie elsewhere also check to see if there is any firmware updates for your brand/model of router.

If there is there do an update , if there is no update then check if you can get a downgraded firmware version , flash the modem and try connectivity again.

If as you say if tried another modem and the problem still exists then go back to point 1 to fix.

Hey man.
Suggest the following...
1. Check connection status on the router
IE to your router adress (found at the bottom of the router - typically 192.168.0.1)
Look for Connection Status.
Should look like this...​
Code: 
Connection Status  
Connection Time 138:15:23 
Connecting to Server Connected 
Negotiation Success 
Authentication Success 
Getting IP Addresses 165.xxx.xxx.xxx
Getting Network Mask 255.255.255.255
Check during 3pm to 5pm. This will confirm whether the router had been able to establish a viable connection to the ISP.​

2. Next check the Connection Statistics.
It will like like this...​
Code: 
System Up Time 260:53:02 
Port Status TxPkts RxPkts Collisions Tx B/s Rx B/s Up Time 
WAN PPPoE 816742 852876 0 179 1934 138:17:32 
LAN 10M/100M 105286 0 0 10 0 260:52:58 
WLAN 11M/54M/108M 1924832 4062023 0 2576 212 260:52:52 
 

ADSL Link Downstream Upstream 
Connection Speed 4096 kbps 512 kbps 
Line Attenuation 8.0 db 6.5 db 
Noise Margin 23.9 db 14.0 db
Collisions should be zero on all three lines - WAN, LAN and WLAN​
Specifically on the WAN (PPPoE - your ADSL) line
- TxPckts are likely to be are moving. If so... then all is ok your router is sending data
via the ADSL connection.
- If TxPckts are not moving then try tracert www.google.co.za...
If it's still not moving then check the following...
* If TxPckts on LAN is moving during the tracert then there's something awry with the router.
Why? Well you can see the router via IE... the tracert is registering on the LAN connection
but the packets are clearly not making it to the ADSL connection i.e.: the WAN connection.
A router restore to factory settings is strongly advised.
* If TxPckts on LAN don't move when doing the tracert then it means that you likely that
your PC firewall is blocking packets. If so turn off all firewall software.
- RxPkts should not - between 3pm and 5pm - be moving - this indicates no data flow to you
and confirms your symptoms...
If it is moving then data is coming through to you but potentially not making it to the LAN.
Could indicate a router firewall issue. Again a restore is advised.
- If RxPckts is not moving and you have confirmed that the modem has connected to
the ISP (in step 1) then again - it's the router and a restore to factory settings is suggested.
​

3. So... if all of the above failed...
Check Windows Scheduler for any software that could be automatically loading at the time.
If you see nothing I'd suggest the following... Set your time back or ahead by 2hrs... if there's something on your PC then you'll see your window of outage shift tomorrow​

Hope this helps.
 
THanks for the replies guys and ill look into it tonight when the problem happens again. When i check router details my line speed drops around 600 to 800kbs. Its a 4meg line but telkoms dropped it to a 1mb so its usally on 1024. As 5pm aproaches its drops and becomes unstable. I did run a tracert and it makes it to the router and past it via the dsl line the thing is each time i run the tracert test times out on different hops. So it will make it to the first domain then the second one times out, run the test again the first hop times out and makes it to the second if this makes sense. I have 3 pc's connected to the router and they all react the same when this problem comes into play. The router firm ware i guess i could try that but as i said i did try another with the same results. Thanks again for the assist and will update on the tests tonight 5pm-10pm
 
I like this idea of recreating the profile.. thanks i will try that as well
 
There's an article floating around in here somewhere which identifies energy saving lights as causing dropped connections.

Try moving the router a meter or two from its current position.
