Hi everyone,

I've tried lots of things and still no joy. Basically, my 5800 (with v50.0 firmware) keeps losing my wlan - even when sat physically next to it. It doesn't lose connection (since it's not connected), it loses (apparently loses) the wlan signal but immediately finds it again - all whilst I am sat watching it within the connectivity->wlan page.

I have sat there, with my laptop running a signal analyser, poling every 500ms and the router's signal doesn't drop at all, yet my phone is sat next to it and every so often it'll show my wlan go from "known" to "unknown" and the signal goes from 100% to none. 8/10 my phone will connect to my wlan for internet use or downloading emails, 2/10 it'll resort to contract WAP since it believes my wlan is unavailable. My wlan broadcasts on a channel that is not overlapped by my neighbours, and my laptop shows a constant 100% signal strength, regardless of other wlans that may or may not be broadcasting (those wlans that do occasionally appear are very weak, and the 5800's dropping doesn't appear to coincide with their temporary appearance).

The wlan is running in 802.11g mode, and is WPA protected. I have tried having no security on it, same problem. I have tried adding the MAC address to the router, same problem. My wife has the same phone, same firmware, and hers does the same thing - except at different times (it's not like the both drop sight of the wlan at the same time).

It appears, though I can't be sure, that if I go in through the connectivity->wlan page and choose my wlan and "connect" to it, then it stays connected and never drops. Unfortunately, this isn't an acceptable work-around since I have configured my phone to periodically check for emails and I don't want to have to remember every time I come home to manually connect, etc.

Can anyone please suggest a course of action or investigation for me to undertake, since this is really, REALLY starting to confuse me!

Thanks for your time,

Mateus

My N96 used to frease when trying to access WLAN, I had the firmware updated and it resolved the problem..

[Mateus]

Cheers for the reply.

I think I am on the latest available firmware - and I can't be certain whether it was doing this on the older firmware or not (I'd like to say "no, no it wasn't" but I can't say that for sure).

If it's the firmware, surely many other people are suffering these same symptoms.....

There was me, hoping I could just change some obscure setting.....  :-(

I had this problem before, and it was basically solved by getting a new wireless router. I went from some cheap 'Zoom X6' thing to a BT Home Hub, and I instantly had no more problems at all. No mucking around with settings or anything like that.

Thanks for the info.

My router's a Sagem and appears to work perfectly with my laptop - but I don't understand why the signal analyser would show a rock-solid 100% signal a few feet from the wireless router the whole time during the test, yet the 2 phones would show the signal dropping out occasionally (and the wlan's status changing from "known" to "unknown" briefly).

Thanks again for replying, much appreciated.

If your router is 802.11n, turn off n mode. Use 1-6-11 rule to prevent interference. Turn off 20/40MHz mode. Use 20MHz only.

Thanks. Router is in .11g mode, channel 6. Sorry to ask, but how/where can I specify 20MHz only?

Don't bother if there's no option. Interference might still be the key issue here. Turn off PC/laptop WLAN, move away from microwave oven, etc....

[Mateus]

Thanks again for the reply.

I believe (always a mistake!) that the wireless router is well placed, and I've tried ensuring the microwave is off (in my house, at least).

However, I have had some success! I have increased my "long retry limit" from 4 to 7 and, of course this could be complete coincidence of interference is the true problem and it happened to have a night off last night (e.g. unknown to me, the neighbours may have turned their offending equipment off, etc.), I had a failure-free night. I set my phone to connect every 5 minutes, and it did! Not one use of WAP in about a 4 hour period (aprrox. 50 successful connections to my wlan).

Does this seem an acceptable fix, or pure coincidence? I'd be interested if anyone can explain whether this seems reasonable.....

(I shall configure my phone one way, and my wife's the other, and then run them sat next to each other this weekend and report results).

Thanks again for your time,

Mateus

[hadimassa]

It's alright to sit next to your wife for a good connection.

[Mateus]

ok...ok...ok...i've been a complete idiot! Changing the retry limit made no difference - i had managed to change my connection settings to only attempt via my wlan and not anything else...so when i checked the so-called successful connections in the log some were empty (zero sent, zero received)! Thus, still broken :-(

[hadimassa]

Yeah, but were you connected to the router? If there's nothing to sync, the log will be empty. I suggest you reset the router and your 5800.Dial *#7370# 12345 reformat, you'll lose all data. Make a backup first and restore without the settings.

[Mateus]

Thanks yet again. Nope, not connected. In fact, posting this is being done on my phone, via wap, whilst sat 10ft from the router...when 30 seconds ago it connected, no probs. Appears random. All very frustrating!! You reckon a reformat it my only option now? Any risks with this? Cheers in advance, mateus.
