Hello , I bought Range Extender WA850RE - installed it and after few hours I have problem with internet connections. The signal of the router was still available but I don't have internet from Extender. I upgrade firmware to the last one, but still I have problems. Is there any solution of the problem?

The same is happening to me, but with a pair of WA850RE and a TL-WR1043ND router.

Yes it is. I flashed OpenWRT and it solves latency and packet loss I was seeing. Sadly I can't figure out how to configure it as a wireless extender.

Have you tried to reset 850RE and what's the hardware version of it?

My WDR35002.4ghz band drops out on my when I use the WA850RE :(
2015-11-05 06:21:13
I have an issue with my WA850RE, but it seems to be slightly different.

After several minutes (sometimes hours if I'm lucky) of having a solid connection, my WA850RE causes my WDR3500 to completely STOP transmitting at 2.4ghz! Prior to adding the RE, my WDR3500 worked awesome across both the 2.4/5ghz bands--I figured adding a TP-Link RE to expand my network was a good idea (keep it "same brand"). But the RE has actually made things WORSE. When I use WIFI signal analyzing apps on my portable devices, I can clearly see both the router and RE transmitting at 2.4hz--after several minutes the router's (and ONLY the router's) signal will just DROP OUT. This does not happen when the RE is unplugged, hence why I am leaving it unplugged :(

Has anyone seen this before, or can offer some suggestions?

I've called and emailed customer support, and they've just told me to reset everything and email them back. I have, and it's taking them days to respond.

And sorry if I'm thread-jacking...I posted my own thread about it here in the RE room about 48hours ago, but my post is still awaiting "moderator approval" I suppose--not happy :(

You can see the two "G" SSID signals, one for the router, one for the RE.




And here you can see that one "G" has DROPPED OUT. It is actually the router that has dropped out, not the RE. The router has never done this before, and this does NOT happen when the RE is UNPLUGGED.

I downgrade it and problem with connection is still available but less not every hour. Maybe next will be to put a openwrt firmware. I am disappoint of tp link support.
