Wifi Congested? What do you think?

[geckoSG]

Dear Networking experts, based on the wifi analyzer result, what would you say about my friends' collected data of the wifi signal at the area where wifi been getting disconnected? Router is FREE DLINK ROUTER by Starhub (looks like CAN design)

Loved to hear your comments and analysis of this

 

[ArcticCheetah]

Either way congestion should not result in total disconnection.

In Singapore where homes are so close to one another, there is no such thing as not congested wifi anywhere, err... except if one set up wifi in the nature reserve.

Congestion (which is unavoidable) aside, the major problem is the very weak signal strength of worst than -70dB. See how 4 or more neighbours have stronger signal strength than you. Perhaps too far away from your own router and nearer to your neighbours' router? You should get your signal strength to be around -30dB and the way to do this is to get another router as a wired AP preferable, otherwise extender (that will have a 50 % speed penalty).

The scenario as follows, router is in an enclosed cupboard all the time. The device that experience frequent connection problem to the router is only about 3~4metres away. Over the weekend, the same device was brought to another residential place to test. This time, device is placed at least 3 walls away (45degree angle from router), but yet, over 60hrs and there is no disconnection at all.

Heat perhaps? Enclosed area not the best idea.

That router is okish

Just maybe too many wall interferences etc

Use the 5GHz signal if possible.

Maybe this is the reason. Furthermore, if is display type with glass door then big problem. If utility type with metal door also big problem. If normal type with plywood door still a problem. Put another super expensive super powerful router enclosed inside the cupboard may also have same problem.

Find a way to bring out the router and give it fresh air to do its work. Don't enclosed all the wifi signal within. Set it free to fill your home with its wifi signal.

If cannot bring out the router then set up a wired AP out in the open.

The router (dlink) does not have any wall interference. Just a wooden cupboard door to clarify setup

 

[geckoSG]

The owner simply setup another AP in his/her own room. Which is estimated to have 2 walls fitted with cabinets n cupboards obstructions. The wireless signal is also very weak for the device to pick up a steady signal.

 

[geckoSG]

And an update. Til today, the device have not experience any disconnection at the test residential premises.

Would you guys actually conclude the problem with the owners router instead of the device is not stable? All that is done is hard set device to link to new WiFi, nothing else done.

 

[geckoSG]

Use the 5GHz signal if possible.

Device cannot pick up 5GHz. On 2.4GHz only

 

[geckoSG]

The thing is, whatever channel to change to, after a while, tat channel will still b congested with crossing signal and will need to re-adjust again. Even putting router on auto will still be overlapped by other 2.4GHz soon

 

[jtjt00]

Device cannot pick up 5GHz. On 2.4GHz only

.
Can your device pick channel 12 or 13 from 2.4GHz signal?

 

[geckoSG]

Can, last time friend already set to either 12 or 13 Liao. But owner surrounding WiFi soon devour those channels also. Then keep blaming device not working, not willing to accept the fact tat the router at only -70db is a problem at such short distance. And an update, the device til today still online somemore at test residential site where 3 walls obstruction between router n area of placement

 

[geckoSG]

Here's a graphical layout at the test site. Til today, the wireless device have not lost connection. 2 walls denote beam area. Signal strength measured at the wireless device area is around -60db at worst and average -45 to -50db.


I guess this test already showed that device is not problematic but problem lies with the owners router and wireless congestion. Test environment wise, there are only 16 wireless detected.

This is not a comparable test, and not a good test to derive conclusion:

1) Different router (Dlink vs Asus)
2) Asus not enclosed in cupboard
3) Asus not blocked by wall (as shown in pic)
4) Which then means that the floor plan also very different from the actual site
5) Which may also means different wifi device
6) So everything not the same

The correct way to test is to bring the Asus to his home and put it in the very same place as the Dlink (replace it temporary for the test). Then and only then can conclude whether is router problem (if Asus perform well) or some other problem (if Asus also same problem).

 

[Mecisteus]

very good points highlighted by upgrade. when making comparisons, all other connecting devices and environment must be the same except for the test subject.

 

[Wongpk]

if 2.4 one is congested then use 5.0 ghz wifi one
cos all home appliances also using 2.4 one

 

[geckoSG]

Actually, there r other walls n stuffs. The diagram is to hightlight the walls in between the device n the router. Unfortunately, owner does not allow the change of router to do the actual test. And believe me, these walls serve as worst scenario than that wood cupboard door in terms of obstruction n distance. If the device can get connect at a longer distance with obstruction. How can it b the device problem at all. Oh yes, this test is done with the ASUS router kept in a IKEA wall mounted cabinet.
