We are having problems with RB951Ui and RB750R2 units that does not want to do remote firmware upgrades. We have replaced 3 units so far and then in the office tried to do Netintall to see if we can get it fixed but problem is we can not even get to point one to have these units in boot mode. We have tried the methods found on the forums so far but it is not working.
These units are on firmware version 6.34 (mibsbe) and we have tried to upgrade them to version 6.43 and 6.44 but no luck at all.
If anybody can help as to how we can get these units into boot mode to do netintall to see if this will fix them or on what we can try to get these units to do firmware upgrades as we need them to be on the higher firmware due to the security problems on the lower firmware versions.
