Question

Internet Problem

I have tried 1 windows desktop, 3 windows laptops, and 1 IPAD on our new business internet setup. The IPAD and two laptops have no problem getting speeds up to 300 mbps. One laptop and the desktop only reach 11 mbps. I’ve tested the desktop and the one laptop on my home system and they work fine there (home is capable of 100 mbps). Interestingly the two computers that can’t get more than 11mbps on the office internet have AMD chipsets. They do have an ac adapter. Any ideas?

Sounds like the 11 megabit connections

Are on machines with 2.4GHz WiFi. I've seen that and usually we try drivers first then move to testing with the newer dual channel USB WiFI sticks.

They are on 5 GHz

All the machines were connected to the 5 GHz. When comparing the 2.4 and the 5GHz, the two machines in question got the same download speed. I forgot to mention in the previous post that the upload speeds are great - close to 40.

Sounds like driver or hardware issues.

To work this we try drivers first then the usual dual channel WiFi sticks.

Also, 5GHz isn't known for distance so you move to 2.4GHz after the 5GHz fades in speed.

Communication Problem

My thought is there has to be some communication problem specifically between those two machines and that modem/router since the computers work as they should with my home modem/router and since other computers get the 300 speed I know that modem/router is working. It's a frustrating problem that no one seems able to solve.

Our office and me by extension.

We've worked this thousands of times. The only time we don't solve it is when the client refuses to use the usual USB dongle/stick. That means the laptop or such has to go into repair so we can change out the WiFi module and get it working in the shop.

Here I summarized what we do and maybe that isn't what you want to read.

-> Another thing. 802.11b would top out at 11 Mpbs. But you don't run into routers with 802.11b enabled anymore. Be sure your router is configured to only be 802.11g or better.

Router

The routers at my home and office are both ac and my USB adapter is dual band ac. Works perfectly at home and gets the max home speed of 97 out of 100 mb plan.....its just a problem at the office.

Then it's something at the office.

Compare what's at the office and home. That's where the issue is if we use the clues given so far.

While I still have fixed this with the usual dongles, sometimes the owner just won't have it.

Difference

The only difference we've been able to find between all the systems that work at the office and the two that don't are the operating systems. All of the Intel and IOS computers work perfectly while the AMD ones do not. I even had the IT department from our local university take control of the desktop and they couldn't find anything.

So a dongle does not fix it?

Sometimes folk really dig in their heels on one of our common fixes.

And drivers are getting harder for IT and techs today. For example in the later W10 versions microsoft turned on an automatic driver update (I find once in a while I have to turn this off) because it will replace a good working driver.

I'm not there to go deeply into drivers and settings but can share my usual fixes. I get the feeling the usual dongle is not an option which puts the machine into the repair shop.

Repair Shop

Have had them in two shops and they are stumped as to what the problem can be. Thanks for trying.... I'll keep playing with settings.

So replacement dongles don't fix it.

That is truly odd. But just yesterday my brother brought in an old laptop that was too slow for the office. It was an AMD but that was only part of the issue.

We ended up doing a few things.

1. RAM went from 4 to 8GB.
2. The HDD was upgraded to SSD.
3. He removed a Quicken app that was slowing startup. It's not in use at the office so just a cleanup.

All this helped and all it does it move it out of the closet and back to work it is just what it is. The E Series CPU can only deliver so much: https://www.amazon.com/samsung-np-rv515-a02us-15-6-inch-laptop/dp/b005okrwkc?tag=indifash06-20

But it does get on the 2.4GHz at over 50 megabits so it's fine for almost everything.

I do have this even older Compaq R3000 and it has the old 802.11b WiFi card in it. That one will not go past 11 megabit unless we use the usual USB WiFi stick.

Answer
Best to contact ISP

Regarding this issue with Wifi speed, it is important to test the Ethernet connection to single out the source of the speed issue. If it is confirmed that Wifi speed is not what it should be for the laptop and computer, you should contact your ISP for further assistance. There may be a number of factors at play here. I have listed some of them, below.
- Internet connectivity settings on the computer and laptop
- the Wifi NICs

Your ISP would likely be able to resolve this issue for you.

Answer
Solved

Problem Solved! Turned out it was software that Dell puts on some of their computers. I uninstalled it and got close to 400 connected by Ethernet and almost 200 on wifi. Still a bit disappointed with the wifi but it sure beats the previous speed of 11!

Thanks for this.

Unfortunately no mention of the make and model was given and there are so many reasons for the above behavior that I can't write them all here. I have to share the methods we use and hope it pays off.

Still puzzling

Unfortunately that only explains the Dell desktop but not the HP laptop. I’ve given up on the laptop since it won’t be used at that office. Since the Dell was able to get 100 Mbs at my home where I only subscribe to 100 but couldn’t get past 11 at the office that was set for 400 my guess is that there must be some controller in the software that senses when speeds of greater than 100 are incoming and shuts it down. Unfortunately, I don’t know much about all of this so it’s just me trying to reason things out.

Beyond a puzzler.

The usual USB WiFi adapter didn't fix it either so this remains a mystery. Sometimes we'll boot up a bootable OS like Linux to see if it's a bum install of the OS.

To repeat a little above.
1. Test with the usual WiFi sticks.
2. Test with Linux. No install required. No learning Linux either. Just boot, run Chrome, run a web Internet speed test.
