Purchased TP-LINK TL-WPA4220 Powerline Extender Kit a while back and have an issue with the extender.

 

I have done both cloning the router config and also manually configuring the extender with the same SSID/Password as the router. I put the extender at the other end of the house and they appear to pair correctly when using the TP-Link tPLC utility.

 

When I connect to the extender I get full wifi strength (using iPhone, iPad and Android phone) but get little to no internet, when I do get internet its completely un-usable and end up having to connect to the main router at the other end of the house to get some internet. When within a closer range to the router we get good reliable internet speeds on ADSL2. 

 

 

 

Anyone seen this issue with the extender? Seen a few posts on the TP-Link forums with similar issues but no real resolution.

Ive installed a few of those exact kits . Generally they work really well .

 

You''ll need to do some basic testing. A process of elimination, there is no single fix.

 

try setting up the 'extender' with a different SSID . Sometimes that makes all the difference.

 

Plug a laptop into the 'extender' via network cable (turn off/disconnect wifi on the laptop)
if that works , then its a wifi issue

 

take the 'extender' into the same room as the router/master powerline unit : again test with network cable
sometimes the power cabling is too noisey/old/bad for these units to work properly, sometimes just moving it to another room helps

 

make sure no surge protecters are in the circuit , ie dont plug them into anti surge powerboards.

 

- sorry if Im stating the obvious, but..
in the kit there will be 2 units. One is the master. That gets plugged into the router , via ethernet cable
The other unit is the wifi/slave(it has more LED's) . That unit gets moved into the remote room.
The remote/slave/wifi unit will still have all the normal wifi issues: it will still have the usual limits on wifi range & wall penetration.
Test it by being in the room as the slave/remote unit (you can get an app for your phone to test wifi signal strength.)

 

Also , some devices dont roam & wont switch properly when more than one wifi access point has the same SSID. So change the ssid on the
remote unit & go from there.

Hi, thanks for the reply, answer to some of your questions

 

1101:

 

Ive installed a few of those exact kits . Generally they work really well .

 

You''ll need to do some basic testing. A process of elimination, there is no single fix.

 

try setting up the 'extender' with a different SSID . Sometimes that makes all the difference. Done this, called it SSID_2, connect to the wifi fine and no/slow internet

 

Plug a laptop into the 'extender' via network cable (turn off/disconnect wifi on the laptop)
if that works , then its a wifi issue I have a couple of devices using the Ethernet ports on the extender and they work fine, get good speed (i.e. can stream a movie from NAS to TP-Link extender using cable through the power to TP-Link Master to Router over cable then wifi to media player)

 

take the 'extender' into the same room as the router/master powerline unit : again test with network cable
sometimes the power cabling is too noisey/old/bad for these units to work properly, sometimes just moving it to another room helps

 

make sure no surge protecters are in the circuit , ie dont plug them into anti surge powerboards.

Also , some devices dont roam & wont switch properly when more than one wifi access point has the same SSID. So change the ssid on the
remote unit & go from there. We're using phones and tablets mainly off the extender wifi. They seem to switch over fine when using the same SSID, and fine when manually switching to SSID_2.

 

 

 

 

 

I'll test out your other suggestions and see how they go.

 

Cheers

since it works OK via Ethernet on the extender, that narrows it down a lot

 

there might be some 2.4G interference, try the extender at the other side of the house
login to the extender & check the wifi settings, try changing channel, see if there is a setting to force wifi G or N only
are you using cordless ph's in house ? any video sender units, wifi security cameras ?
try turning off all wifi devices except 1 laptop/tabet/ph to test with

 

sounds more like its faulty though : since wifi connects & throughput via network cable is good.

Had a quick play over the weekend, after setting to G (or might have been N, can't remember which I did now) only there was a huge improvement straight away with internet via the Extender, YouTube didn't buffer and general browsing was fine. However over the rest of the weekend it was better but still a bit hit and miss, sometimes it worked fine and other times it was slow.

 

Answered some of your questions above also.

Still ongoing issues, sometimes its good but most of the time its not.

 

Been reading through this: http://www.vexperienced.co.uk/2014/11/24/wifi-problems-with-tp-links-powerline-starter-kit-wpa4220/

 

Has some suggestions on modifying the wifi Advanced Settings.

 

Anyone else played around with the settings to get better performance?

They sound pretty problematic units.

 

I note there was a link in that uk thread that points to this page:

 

http://www.tplink.com/us/claim/

 

Basically in the USA they have said if you arent happy bring them back and we will give you a full refund - no questions asked. Pretty big step for anyone to offer that for their own products!

 

That WPA4220 is specifically mentioned.

 

Print (copy that page link) and take it back to whoever you bought it from.

 

Actually the other thing that might help you is signing up to the TP-Link site and logging a ticket. If you give clear enough details (and maybe even mention that USA return program) their techs sometimes tell you to arrange for a replacement. I had that with a flaky TP-Link ADSL router I bought a while back from PBtech. Seems there was a version 2 of the product that had some odd chip/behaviour under some circumstances. After a couple of try this/try that notes on the call they said "please take it back and arrange a replacement" - I made sure I got the newer version 3 model and it was rock solid. Printed the email (complete with references) for PBtech and they didnt even blink at replacing it. retailers like paper trails!

Ive intalled maybe 6 of those exact TPLink kits . The only issues I had was one pair needed a reset (after a year) and one rooms power cabling was too old for it to work.
Other NZ techs have installed heaps of those as well. In general they are very good .

 

But , here's the kicker
with wifi , with powerline , its allways just a best effort sort of thing.
Wifi is allways just a 2nd best medium.

 

If it doesnt work , you need to consider running cables .

 

The next step, since the powerlines ethernet port works 100% (as you tested), connect a wifi access point to that powerlines ethernet port
& see how reliable that is.

Thanks for the tips. Will try a reset again and see how it goes.

 

I'm 'chatting' online now to their support, as soon as I said I have this issue they said they'll send me a replacement, as if its a known issue.

TP-Link support is generally pretty helpful. I have dealt with them several times and they always gave good assistance.

Finished a chat session with their Tech Support, as soon as I said my issue and they asked a couple of questions they offered to replace the extender. My extender hardware version is v1.0 and apparently the replacement extender will be v1.2 and they assured me it would resolve my issue. They wouldn't say whats difference in the hardware versions.

 

Once I get the new unit we'll see how things go.

Latest update.

 

TP-Link are sending out a new extender with a newer firmware version that resolves this known issue (not hardware version as I previously stated). This new firmware isn't available on their website yet so they are just replacing the units instead.

Hi, I had a number of issues with my setup, what resolved my problems was to give the TPlink a static IP address at the router.

Latest Update

 

Got my replacement extender and the firmware wasn't newer, same as the latest release on their website.

 

Has the same issue though and I seem to have narrowed it down to mobile devices, on laptops the wifi connects fine and no slow internet. Connecting via iPhone, iPad, Android phone the internet is slow or no-go at all even though the wifi strength is full.

That problem can happen with many different routers - usually fixed by changing the security type to WEP or updating the router firmware. I see it especially common with iphones or apple devices causing other devices in the house to slow down just simply by being connected.

 

With the TP-Links, I probably have about 80 of them which we manage on behalf of customers and they generally work really well. A little annoying you cant set a static ip address in them but other than that they are great.

 

 

 

Powerline technology is really hit-and-miss and so its understandable they are offering a money-back guarantee with so many people that claim the technology is bad because it hasnt worked in their house.

 

9/10 times we will send a set out and the customer will plug it into a 6-way surge protecting multiplier which the instructions say not to, and then they claim their internet isnt working. Upon a site visit we have to put a double plug in to bypass the surge protector as they suppress the data noise.
