ok one question...should my MTU be 1500 or 1494 (1494 is what i figured it out that it should be by using a linksys knowledgebase article...basically i pinged google with some settings and they said to keep readjusting until i got a fragmented packet...anyway i ended up with 1494). so which should i do in that screenshot you gave me? the router is set to 1494 currently.

ok...i'll do that right now and post afterwards, thx

I posted in this thread about some problems I had with optonline being only 19%: https://testmy.net/forum/t-6920'>https://testmy.net/forum/t-6920 I was at 19%...I changed my MTU to 1494 on my router (followed the instructions in a linksys knowledgebase article about how to determine the optimal MTU), downloaded DRTCP, and changed the MTU on my computer as well. After doing that, I am now at 26.5% of optonline's average. :::..

I looked at VanBuren's cablenut thing, but didn't know what to do, and was scared to change anything or do anything withour knowing what I'm doing. Just a quick recap of my setup: I have a split-level house, downstairs is the cable modem (motorola surfboard) and a linksys wireless router right next to it. Upstairs are two desktop computers, both with usb wireless network adapters. Both are running Windows XP Professional. I had 5.8 ghz phones, but they're all unplugged. I do have two old 900 mhz phones, and could install them...but really, I only need my one corded phone setup for now. So...what else can I do to improve the speed? I don't know anything about RWIN and haven't changed any settings. Seems like I need to know the advertised speed to calculate the correct RWIN? I spoke to optonline over the livechat and they said 10,000 kbps as the advertised download speed? Is that even possible? thanks very much

yeah...well all the phones are unplugged now. i found out using linksys's knowledgebase that my MTU should be 1494. i haven't changed anything in my registry, but i did download DRTCP and i'm going to change that. so after doing that, if i still have problems, i'll post in the make it faster forum...thanks very much

umm...why was this moved to optimum online? this applies to making a connection faster, it has nothing specifically to do with optimum online as netmasta showed. i just put optimum online as the topic in case someone had similar problems, but now i see it's a general networking issue. i bet a lot of people don't know this about 5.8 ghz phones and MTU...

thanks i think i know what a BIG problem is: http://www.tomsnetworking.com/FAQ-37-Performance-16.php#481 most 5.8 ghz phones ALSO transmit on 2.4 ghz, so they use both...the only safe ones are TRUE 5.8 ghz phones (tom says uniden) OR 900 mhz phones.... i bet that is causing a lot of the problem!

one other thing...is it possible that my wireless network adapters will figure out the right MTU and set it correctly in the computer? or is this a software thing i must do myself? because the only thing i changed was on the router itself.

Thank you VERY much, netmasta that is exactly what i was looking for.

Someone sent me a PM telling me I'm rude...I'm not trying to be rude, I'm just frustrated that hours of Linksys tech support from an Indian call center haven't helped at all. I already know the basics of networking...this isn't a basic question that any computer literate person could guess at. So if someone is aware of the pros/cons of lowering MTU, please let me know or direct me to where I can find out. That's all...I'm not looking to get into a pissing match, and honestly I don't think I was rude, but for anyone who was offended, I'm sorry.

Then why would I only be running at 20%? It can't just be the plan, and I don't download enough to be capped by far. Look....I just want to speed up my connection...if this isn't the forum for that, can someone please kindly tell me where I should go to figure it out? I kinda already know what's been said so far intuitively....specifically, I need to know about MTU's. thanks

so does anyone here know ANYTHING about MTU's?

So...does anyone know how I can increase this, and what are the pros/cons of lowering MTU further?

humorman.....i'm not goign anywhere near 11 mbps... even if my wireless network was capable of 54...i'm still not even pulling 2 mbps. i'm not using my wireless network to its full capacity, so why would it matter if i increased it?

hmmm that optonline speedcheck site says i'm doing 2089 kbps??

but are you on wireless jimmy? what do you think ic an do to fix it? i was very surprised i was only at 20% of optonline

no i don't think so.... 11 mbps is still faster than the speed of my cable modem, and i have a good signal. why would it make a difference?

Upstars are two desktop computers- one has a Linksys Wireless-B USB network adapter, the other has a Belkin 802.11b wireless usb adapter. Why is it only at 19.54%? Is that because of how many people are using it with a wired connection? There are no 2.4 GHz phones in the phone, they're all 5.8 GHz. I spoke to Linksys about this, and the guy had me lower my MTU to 1492 and that improved it by maybe 10 Kbps, and that test I just did is with the lowered MTU. What can I do to improve this? Should cable be like twice the speed? I very much doubt I download enough to be capped. thanks Why is it only 19.54%? There are Excellen
