Just throwing it out there.

 

What is the top speed of a wireless router ?

 

Looking online, theoretical speeds and real world speeds can be confusing.

I have an NBN connection 25/5 but my wireless speed peeks at 12.6Mbps.

 

Is that a good wireless connection ?

I am not fussed if it is slow, just wondering as I am paying for a faster connection.

Thanks in advance.

TH.

12.6 Megabits per second (note bits not bytes) is somewhat slow for modern Wifi. But it varies depending on what standard, quality of signal (also consider interference), and how many devices are on the WLAN.

 

Note of course the connection between device and AP is limited to the capability of whichever is lower specced.

The wiki article has a table of expected top speeds https://en.wikipedia.org/wiki/IEEE_802.11#Protocol

 

Also note with the earlier standards (before 802.11n) the entire bandwidth is divided among devices including the AP, and including upstream/downstream.

Whether your connection could be considered "good" - you'd need to compare it to a best case scenario given your current network topology.


If you have an Android device, Wifi Analyser is a handy tool. It can give a graph of available networks and has a channel view mode so you can see any overlap/contention that might be going on.

From the sounds of it, 12.6 megabytes/s = 100 megabit/s which is 802.11n which isn't slow but the faster standard is 802.11ac (150 to 1000 megabits/s) on 2.4Ghz band.

802.11n can go higher still but every chance a decent 'net connection can exceed what your Wifi is capable of when you consider the WLAN bandwidth being shared by a dozen clients.

 

But yep - a good idea would be to try and deduce best case speed by doing Speedtest with cabled connection and nothing else on the local network, prefereably during a quiet time.

Then you can guestimate if you're going to max out the Wifi capacity. If so then try and run one or more devices cabled. I've always just left my main machine that way, not much sense changing it given it's rarely more than a few feet from the router.

25/5 is bits, not bytes. I figure he's comparing apples with apples.

Had a go at changing the settings on the router.

After a few tries I managed to get the same speed as cabled.

One day I will buy a better router with an AC connection.

 

Thank you for all your help.

Just think of Wifi as being a bit like the old token-ring.

 

When they first produced the standard there were plenty of weaknesses and shortcomings.

The fact it relied on the AP to hold the whole thing together is one of them.

But they're ironing some of them out, each newer standard tends to bring improvements aside from extra speed.

Beam forming is probably the best development/addition to the standard in a while.

I have a UniFi AP AC Lite, and I can honestly not tell the difference between wired and wireless any more.

Strange my little Tbook can pick up the wifi 4 rooms away with 3-4 bars on Wifi but downloading i get heaps of crc errors and speed drops to 10k/s. So does that mean something between wifi and Tbook is interfering with the signal?.

 

I got my PC which is right next to wifi ,got a washing machine and a fridge in the path. But when i move Tbook back into same room as Wifi source its back to same speed as my Adsl connection and no crc's.

What's giving CRC errors?

 

Network connections are such that errors are expected even on wired and the normal course of things is that the operation is just retried, and such errors aren't echoed to the user.

No idea. On crc errors.

Fridges are 'noisy' he's probably the culprit.

But standard 'distance' will have the same effect. Pretty easy to test really, unplug the devices between the two momentarily, then see if the problem persists.

 

If it does, its just the effect of distance and walls.

If it doesnt, then your fridge and PC are electrically 'noisy'

It's worth doing a scan with something that gives channel readouts and strength.

 

e.g. Wifi Analyser for Android.

 

I have a neighbouring network that was overlapping with the channels my one was using so I changed it to use a free area.

I wonder if asbestos can interfere with Wifi signals? My room is built with this horrible stuff and strange when i moved my mobile phone on Wifi from out of my room the signal on 4g went higher and wifi maxed out.

Damn router modem reset when trying to activate wifi. Damn Windows Firewall activates telling me something was trying to change User data.

 

My little Tbook did a critical update ,thinking MS flooded my router with data forcing a reset. And it was 69 days since last reset ,damn broke the record of 75days.

in my little Tbook its a 802.11 thing for wifi ,but on some sites it has n/b/ or something like that. Could it be a setup issue on the Tbook causing the crc errors.

 

In the actual Tbook i check MS for an updated driver but it says it was up to date. Still shows 2015 but a MS driver ,but in the actual Program Files Directory is a copy of Broadcom drivers for it. On the ASUS Transformer help forums it says to use Broadcom drivers but MS driver update will not recognise them.

 

I remember this used to happen on updating GPU drivers sometimes when you set up a new PC. But not sure if Win10 could blocking the update.

 

Thinking out aloud here ,maybe if i copy dir of Broadcom drivers on too a USB device and see if that works.

 

Only have a MS phone so i cannot get a Wifi diagnose thingy app to see if signal is the problem.

 

Looks like wifi is a big issue on these Transformer books going back to 2013 when first model was released.

Some sites? You mean access points as in when you go out in public?

No doubt some places will still be on 802.11g, entirely possible some might even still be on b.

Not that it matters much. Get a few people using most "free" public wifi connections and it's like going back to dialup regardless of which standard it is.

From my Tbook to my Modem Router Wifi ,it gets heaps of crc errors as i previously mentioned.

 

Thinking maybe it could be a protocol issue. With drivers on each end.

Might be interference from neibouring networks. You should be able to change channel in your router settings. Try one of the middle range like 7 or 11.

I have about 7 networks overlapping my house. Is their anyway to know what is using what channel.

NetStumbler on Windows will do the trick.
