Hi,

Thank you for your help with my:

Allied Telesyn
AT-FS708
10 BASE T/100 BASE TX
8 Port Fast Ethernet Switch

Thread URL:

http://www.daniweb.com/techtalkforums/thread32824.html

I connected the switch as you said and ran the network wizard on both machines and it worked.

I have another question. I am running XP. I have 2 computers, 1 brand new (5 mos.), and 1 about 5 years old. They both have been networked together with a simple (1) crossover ethernet connector. File sharing was fine and I would connect to dial-up individually on each machine.

Now, currently:

On the new computer which has an ethernet card, I have no problem with file sharing between the two machines and the internet connection is fine with the new DSL.

The old computer has a USB to ethernet adaptor. (which is the way I have been operating it thus far) (it has never had an ethernet card) The file sharing between the two machines still works fine, as it always has. The problem is that the internet connection will not establish through this USB to ethernet adaptor on the old machine with this new DSL connection I have. I have previously been operating with dial-up.

Why do you think I can not connect to the internet on the old machine? I am able to ping google and yahoo with 100% success. Sometimes I can connect to google's homepage in internet explorer but then it freezes and will not continue. (but 99% of the time it is "this page can not be displayed")

Is the USB to ethernet adaptor the problem? Is it as simple as I need an ethernet card in this machine? And if that is the answer, why am I currently able to do file sharing through the above Ethernet Switch between the two machines?

Thanks in advance.

Questions? Please ask.

— the symptom set (local file sharing and ICMP work, but HTTP mostly fails) usually points away from a pure link-layer fault and toward one of three areas: browser/proxy settings or a client-side firewall, a TCP/MTU/path-MTU problem, or flaky USB-Ethernet driver behavior. is right about keeping everything in one place; the checklist below helps isolate which of those it is.

Start with quick diagnostics (run these from the old machine and capture results):

ipconfig /all
tracert google.com
ping -f -l 1472 google.com
ipconfig /flushdns
netsh int ip reset
netsh winsock reset
  • Check Internet Explorer (or the browser) for a configured proxy: Tools → Internet Options → Connections → LAN Settings — ensure no leftover proxy or dial-up setting remains from the old dial-up setup. A bad proxy will stop HTTP while ping still works.
  • Verify the default gateway and DNS entries in ipconfig /all match the router/modem on the network. Traceroute (tracert) shows where TCP/IP traffic is failing.
  • The ping -f -l test diagnoses MTU/fragmentation problems (PPPoE and some DSL setups lower the MTU). If large pings fail but smaller succeed, a PMTU issue is likely.
  • Resetting winsock/TCP and flushing DNS often clears corrupted stacks from old dial-up/ISP software; a reboot is required after those commands.

If the above doesn’t fix it:

  • Temporarily disable third-party firewall/antivirus web shields and try another browser.
  • Update or reinstall the USB-adapter driver, or test with a known-good PCI/USB NIC (swap hardware) to rule out adapter-level faults.
  • If direct router connection (bypassing the switch/USB path) restores normal browsing, the adapter or its driver is the culprit.

Cautions: winsock/TCP resets require a restart and can affect VPN or custom networking software. If MTU is implicated and the ISP uses PPPoE, set the MTU accordingly on the client or router.

javamann... Stick to one thread. There was no need to create this thread since it doesn't ask anything that is off the topic of your other thread. Furthermore, you do not need to link to your thread in the introductions tread since it wasn't an introduction, it was simply the exact same post as the first post in your other thread.

Sorry about the thread thing... I'm still learning :)

Do you have an answer for my problem?
