Pi (1st generation) Model B internet connection trouble

I'm new to the community and I just started using my Raspberry Pi (1) Model B. I installed the latest jessie with Pixel desktop, but Chromium is timing out for every website, even Google. I'm connected by ethernet cable and the cable works; I've was able to get Chromium to work on a Pi 3 Model B with same connection.

I'm very new to Linux and really don't know much about it. What can I do to get the browser working on my older Pi? I'd like to download the updates and install files from the internet using Chromium. Any help is welcome.

do you have the RPi1 with 256MB or the RPi1 with 512MB?
i am currently flashing Raspbian Stretch to my RPi1 256MB... if it is done, i can tell you if chromium is working there.

EDIT: actually i installed 2017-08-16-raspbian-stretch.img to a 16GB SD card and plugged it into my PRi1 (rev.1) with 256MB.
just without any modification of the configuration, Chromium works more or less.

it is able to download webpages and render them. but extremly slow.

open "https://duckduckgo.com", page takes ~3 minutes to begin render its content. after total time of 9 minutes, the page was fully loaded and the CPU goes from 100% down to ~15%.

open "https://google.com", page takes ~3 minutes to begin render its content. after total time of 12 minutes, the page was fully loaded and the CPU goes from 100% down to ~68%.

so, from my side, there is internet working out of the box - chromium is working on a RPi1 rev.1 256MB at 700MHz CPU.
but to me it is not usable, because it is that extremely slow.
(normally i have only the lite version installed on my old RPi1 - that makes more sense to me)

i did not over clock the CPU!
i did not changed the memory split!
i did not update or upgrade anything for that test!
i did not run raspi-config nor rc-gui!
i just flashed the SD and boot (and auto resize).

you can over clock the CPU up to 1000MHz, that makes some things working faster, but maybe also a bit more unstable.
you can increase the memory split but on a RPi1 rev.1 with only 256MB, there is not much left when you increase the split.

I have the RPi1-B with 512MB, no over clocking, just straight out the box with a 16GB SD card and the Raspbian image.

When I use Chromium, and try to go to Google.com, chromium gives a timeout message, and does not load the page. Every web page I try to view using Chromium always times out, and Chromium displays the timed [Retry] page.

Again, I'm completely new to Linux, and the Pi, so I have no idea how to trouble shoot this.

Any help is appreciated.

is only chromium affected from that time out?
i am not familiar with chromium, so i don't know, what will let chronuim run into time out.

you can successfully ping to google?

Code: Select all

pi@raspberry:~$ ping google.com

you say you use the latest raspbian jessie image. but the current image is raspbian stretch now from 2017-08-16.
will this make a different?

I've tried ping 8.8.8.8 which gives results, but some tries have errors. for example:

Code: Select all

64 bytes from 8.8.8.8: icmp_seq=117 ttl=57 time=2.19 ms
I didn't realize there was an update for jessie image on 2017-08-16. I'll have to download that and try it, that may help. Also, I'll try and ping google.com, later tonight, and post the results.

Any help is appreciated greatly.
