I have a problem with my dial-up connection. I am using KPPP under my RedHat 9.0 system. Yesterday everthing was working just right but today I have such a problem. I am able to set a connection and it seems that connection speed is 45.2 KB or so, but I cannot open any web site, or connect any thing else, because it is so slow. I checked the details sections on the KPPP connection properties window thingie and I saw that, my max speed cannot go above 1 KB/sec. I tought that it is interesting I don't know how did I manage that, I didn't reconfigure anything. Anybody knows the reason why?
Appreciating any answers, thanks !

What kind of modem do you have? This will make a difference. I have a external US Robotics 36.6 Faxmodem.

I have experienced extremely slow internet with kppp on one occasion. My connection speed was turned up to the maximum of 460800. Try changing the connection speed to something more realistic.

click Setup->Device Tab and go down to connection speed. I fixed the problem by setting it to 57600.

I have Redhat 9.0 stock distro.

Hope this helps,

Ben

The old telephone lines in my neighborhood are only good for 26.4 K and yet I am able to browse the Internet without any problems other than being just a little bit slow. I have an external 56K serial modem.

I have installed several operating systems on my computer. Whenever I install a new operating system I do not always get it set up correctly for connecting to my Internet provider correctly on the first try. Usually what happens is that I am able to establish a connection but am not able to view any web pages. I then have had to go back an check all my settings until I find something that is not correct. One mistake I have sometimes made is not getting my username correct.

I use Red Hat 9 and with the help of VMware I can boot up other operating systems in a window (or full scrren) under Linux at the same time. The operating systems that I sometimes run in a Window include Windows 2K, Windows NT 4.0 and Red Hat 8. With most of those operating systems I did not get the Internet settings correct on the first try. With all of those operating systems I can now successfully connect at 26.4K and view web pages. It is the same speed that all my neighbors get with their computers too.

I am only moderatly knowledgeable about Linux but, you should probably check all your Internet provider related information. There are several differnent tools for setting up internet connections under Red Hat 9. With Red Hat 9 I first used the Neat command to set up my Internet connection. I then went into Mozilla and set up some additional information. I then also did the same with the Konquoror and Galeon browsers. Perhaps your problem really is your 1KB/sec speed but check the settings too. I should add that I only half know what I am doing whenever I set up a dial-up connection. I have never used KPPP. I use Gnome and usually use something that seems to be called Network Device Control. I see there is something called KPPP in one of the menus but I have never tried using it. I am using Red Hat 9 at the moment as I write this.

Have you set MTU and MRU? Set both of them to 296 to make dialup a bit more responsive.

thanks for the commands, here is what happens...

first of all, I am using a good modem for Linux which is USR external Sportser 56K

second I am able to connect to internet with a good speed on Windows environment

third, however in KPPP details dialog it seems that my max speed is 1K, and that is so, ý cannot connect to anywhere, that is too slow.

I am new to these subjects, how can I set them?

well I tried that also, but it didn't work?

I wonder if I did something related to firewall, or the ports, I mean I somehow, limited my connection speed to 1K with some bandlimiting command, I don't know, maybe I did my accident, because these days I am trying to share internet connection with my room-mate and try to set some firewall properties.If I did something like that, how can I set my firewall properties to default.

thanks again for the comming answers !

this is good, now you know your modem and your ISP is ok.

I wouldn't worry about phone line quality if you can connect fine in windoze.

this wouldn't neccessarily speed up the total bandwith though...

This sounds troublesome. If your Internet speed was normal before you did this, than that is most likely the problem. A good habit I make whenever I do things to my system is write down exactly what I'm doing, as I do it. Then If I break something I can go back and fix it later. This works well if your not sure what you are doing in the first place. It's an excellent way to troubleshoot these kinds of things.

I don't know enough to say what would cause your internet to slow that much. Could you give us a hint as to what you did exactly?

If you broke something bad enough, try reinstalling the core rpms off the cd (without formatting your partition) and see if it might reset your firewall configuration back to it's default state.

Thanks everyone I guess ı solved the problem in a way or so. I think kppp weren't able to start ppp0 for some reason which I still don't know. But I tried to connect by Red-Hat inernet config tool, which works fine now. Anyways, I am upgrading to cable connection, I wish I won't have any problems there
thanks again

I am having the same problem! I can connect at 45,333 but on the graph
it shows a single spike and then a spike every few seconds but no page load, no errors, just sits there. Didn't do any firewall thingy, either. Wouldn't you get an error if KPPP couldn't start ppp0?
Thanks everyone for any insight. If it weren't for these forums (I like THIS
one) Linux would be screwed.

I have the same EXACT problem, too.

I have Mandrake 9.2 installed, an Intel536ep 'hardware' modem. When I was using Red Hat, the internet went fine. Then I installed Mandrake 9.2 and now I can connect to my ISP at 54,666, but no pages will load!

I have updated the kernel to version 2.4.22-26 and installed the kernel source headers, but still, I think the modem compiled all right...otherwise I wouldn't be able to connect at all, right?

My problem is a bit different. I can connect with RH 7, using kppp with a dial-up modem. I see the "connect" and that I am connected. When I try to use Netscape, it can't find any websites. It acts like there is no connection.

Any ideas?

Rockee:
Why is your problem "a bit different"? Sounds like the same problem we're
having. Pages won't load with the browser. Please post if you find an answer.

To be more specific, it's "different" since I never have been able to connect to any websites, while "aweir14150" said was able to connect using Redhat, but not Mandrake.

Here's how I fixed my problem......
1. edit the /etc/resolv.conf file with:
search (yourisp.com) (no www)
nameserver (your isp's primary DNS (208.xx.xx.1)
nameserver (your isp's secondary DNS (208.xx.xx.2)
2. after saving the file, UNPLUG your network cable from the switch or
your NIC.
3. Give it a shot. This worked for me.

I guess the system was trying to connect me via network since I had the usual network address in my /etc/resolv.conf file (192.xx.xx.x).
Hope this works.

it is very easy to resolve the problem. you must go to the k menu > system settings > security level and select medium or lower level to enable kppp transfer data up to 1 k/sec
