>Hi, Arthur Arthur Frank wrote in message ... Hello, I recently "upgraded" the network card in my PC from an Accton MPX NE2000-compatible ISA card to a 3Com 3C905 PCI card, and I've run into a little bug that I can't figure out. >Conguraturation, Did you change cfg file to frame size and buffer , If you run window 3.1 >you might configure by yourself not like plug and pray like win95. Now, every once in a while, my NS/VT connection to the 3K gets *really* slow. The only things affected are: block mode transfers, downloads with the terminal emulator (Minisoft), and Qedit for Windows. Otherwise, if I'm just doing command-prompt stuff, everything seems a-ok. >May be network has not enough bandwidth with longer buffer size(?), smaller buffer(IPX/SPX) >run quickly transfer fast, but perhaps longer buffer(TCP/IP) have to retransmitt over period time >to clearing all the frame(?) might be tried couple of time to get clear transmission (?)... The problem is especially bothersome because it's intermittent. Everything seems to work fine and then - boom! - block mode screen redraws get *s*l*o*w* and downloads don't work at all. I can't tie the problem down to any other apps I'm running -- sometimes the termulator is the only thing going. To clear the problem, I reboot and try again. >Check network traffic, emulator may be waiting data from network... Is it perhaps becuase I'm now loading both 802.2 and 802.3 frame types? That's the only thing I've changed, besides the card. And, in case it matters, we're still on Win 3.11. >Dos configuration file is very tricky, unless you know exactly all the parameter like frame type, >frame buffer size... WIN95 plug and pray fix this problems. >Definately Improvement over win95 win3.1 is not gearing to network, It is DOS with GUI >interface, WFW 3.11 just tring to mimicking Network, WIN 95 or above have kind true network >Interface with 32 bit mode. >Do not settle for less money, product may cheap, but total cost of owner ship may be way over >to operating simple task... >TIA, >Just my $.02 >Peter C.
